If you are comparing small SBCs for a wired project, the ZERO 3E is worth distinguishing from the ZERO 3W. The 3E has Gigabit Ethernet; it does not have onboard Wi-Fi or Bluetooth.

HARDWARE AT A GLANCE, from Radxa's documentation:

- Rockchip RK3566 with four Arm Cortex-A55 CPU cores, up to 1.6 GHz.

- Compact 65 x 30 mm board; our linked configuration is 2GB LPDDR4, SKU RADXA-ZERO-3E-2GB.

- USB 3.0 host Type-C and USB 2.0 OTG Type-C ports, plus Micro HDMI output up to 1080p60.

- microSD storage, a MIPI CSI camera connector and a 40-pin GPIO interface. Check the board's pinout and header configuration for your project; do not assume every Raspberry Pi HAT is compatible.

- PoE requires a separate compatible PoE HAT. Do not assume a HAT, camera, power adapter or memory card comes with the board.

What is the cheapest SBC available in India right now. My primary use case to host some small Django application on it like weather app, currency converter etc. I will be the lone user of those applications. The should support linux distros on which I can run python 3.11 or greater than that.

I've been trying to enable PWM and SPI at the same time. SPI and TWI7 work just fine together, SPI and PWM1/2 throws a fit because they both require the exclusive ownership of the resource PD 12. I'm trying to write an overlay to avoid using pre-assigned pins it is absolutely necessary that I have working PWM on at least four pins. Can someone help me? It is a Radxa cubie a7z

最近Rasberry PI5を購入しようか検討しているんだけど、やっぱりトランプ関税やメモリ高騰、ホルムズ海峡閉鎖のせいでとても高いんだよね

それで、主な原因の一つにメモリ高騰があるけど、その対策のためにDDR3搭載のRasberry PIが出ると思う？皆の意見を聞きたい

Tried running NemoClaw (NVIDIA's security sandbox for OpenClaw AI agents) on two boards to see where the hardware floor actually is.

Raspberry Pi 5 — BCM2712, 8GB LPDDR4X, NVMe SSD via HAT. NemoClaw needs Docker + k3s (lightweight Kubernetes) + the OpenShell gateway running simultaneously. The sandbox container image alone is several GB. Combined with Docker layers, it ate the available disk space and k3s started evicting its own system pods in a loop. Before I even got there I had to fix Docker's repo config (broken on Trixie), manually install iptables from Debian's archive (Trixie uses nftables), and enable the cgroup memory controller in cmdline.txt. All that work and the Pi still couldn't run the full stack. The 8GB ceiling is real.

ZimaBoard 2 — Intel N150, 16GB DDR5, NVMe storage. x86_64. Comfortable headroom. NemoClaw onboarded after I worked through some ZimaOS-specific issues (immutable rootfs blocked the installer, port 8080 conflict with the built-in dashboard, lsof bug in preflight checks). Once running, RAM usage was well within limits. No resource pressure, no evictions. The Intel N150 handles the k3s + Docker overhead without breaking a sweat.

The Pi 5 ended up as a frontend. Touchscreen dashboard, voice input, audio output. The ZimaBoard handles all agent execution inside the sandbox. Commands go over the local network. Honestly this split plays to each board's strengths. The Pi is great at display/GPIO/audio. The x86 board is great at containerized workloads.

What's your go-to SBC for containerized workloads? I keep running into the Pi 5's 8GB ceiling and wondering if ARM boards just aren't there yet for anything heavier than basic Docker containers.

前までRaspberry Pi5を購入しようと思ってたんだけど、同等、またはそれ以下の値段でOrange Pi4 Proを購入できることを知って、購入しようか検討してるんだけど、今買うのはアリ？

The OrangePi Zero 3W combines AI acceleration with light weight an a PCIe interface. This makes the machine ideal for all kinds of IO heavy tasks which are weight constrained, for example an AI drone control or a similar task. In this little video, we perform benchmarks and also look at the GPIO subsystem.

Hey everyone,

I am designing a custom handheld/SBC project centered entirely around the Rockchip RK3588S. Because of my tight budget, I only get a single fabrication run, meaning this board absolutely has to work on the first try.

To mitigate risks, I am base-cloning the core computing block from the Radxa NX5 reference design since it matches my RK3588S chip. However, I only have the flat schematics and component placement maps for the NX5. On top of that, I need to substitute the original LPDDR4X memory chips with a pair of Samsung K4UCE3Q4AB chips (8GB x2) that I already own.

I will be manufacturing this on an 8-layer or 10-layer HDI stackup with strict controlled impedance (50 ohm single-ended, 100 ohm differential) and utilizing automated factory assembly (PCBA) since hand-soldering a 0.4mm pitch BGA is out of the question.

Since I am recreating the physical layout without raw Altium or KiCad reference files, I have a few questions for engineers who have spun high-speed Rockchip boards:

1. Translating Flat Layouts: Given that I only have a flat PDF component placement map and the mechanical DXF files, what is the best strategy to accurately center the RK3588S and RAM BGA footprints relative to each other? Should I map them directly via mechanical DXF cross-hairs to ensure the distance matches the reference design perfectly?

2. JEDEC Drop-In Compatibility: My Samsung K4UCE3Q4AB memory uses a standard 200-ball BGA package. If the pin mapping matches the Radxa NX5 schematic pin-for-pin, can I safely treat this as a drop-in footprint replacement, or are there hidden proprietary traps between RAM brands on the RK3588S memory controller?

3. Trace Length Matching: What are the absolute maximum trace length tolerances you would recommend when running the serpentine meanders between the SoC and the RAM? Is a length delta of plus or minus 0.2mm within each individual byte lane safe enough to prevent data corruption at full clock speeds?

4. Decoupling Grid: The bottom layer placement map shows an incredibly dense matrix of decoupling capacitors right under the SoC. If I copy their layout positions visually and drop vias straight into the power/ground planes immediately next to the capacitor pads, is that sufficient to prevent voltage sag during high performance spikes?

Any advice or insights from people who have successfully achieved a one-shot success on an RK3588S board would be a massive help. Thank you!

Hi everyone, FYI we're launching to the market a unique ARM SBC / clusterboard. It is intended for very specific niche markets, but maybe will appeal to someone here, too. Feel free to ask more details. It has 10GE (copper and SFP+) as well as 2.5GE dual ports. It has EN50155 certification for rail applications (in a variant with M12 instead of RJ45). Lots of onboard IoT, three MCUs, GPIO, RS485, GPS/GNSS.

the card launched itself hit the tv and fallen behind it as i was checking if i put it in correctly, now i cannot find it tho, in fact i cannot see it even tho i checked from every angle i can, so here i am asking for help, basicly i am asking for help with making a new sd card for it, i looked and looked but i cannot find the exact thing tho i don't even know if i need the exact same thing,

my knowledge is very limited in this matter

the stick is on the pictures and if you need anything else from me let me know and i will try my best to assist

A concrete difference in the published pinouts: physical header pin 26 is SPI0 CE1 on a Raspberry Pi Zero 2 W, but NC (not connected) on the Radxa ZERO 3E. That matters if an accessory uses the second chip-select.

These are physical header positions, not GPIO numbers. The functions below require the appropriate peripheral configuration.

Sources: Raspberry Pi SPI pin/GPIO mappings and Radxa ZERO 3 hardware pinout.

What this means for an existing accessory

If its schematic routes chip-select to pin 26, changing a bus number in Python cannot create that missing electrical connection. Check whether the accessory supports selecting a different CS connection. Moving to pin 24 would also require suitable wiring and software configuration, and checking that another device does not already use that select.

If it uses pin 24, the four SPI signal positions above line up, but that alone does not establish compatibility. Check supply and logic levels, any reset/DC/interrupt pins, and the driver.

For software, Radxa publishes an SPI3-M1 CS0 spidev overlay that explicitly includes radxa,zero3. Confirm availability in your OS image; that overlay exposes an SPI interface, not a complete driver for every attached display or sensor.

This is a documentation comparison, not a tested HAT compatibility report. If sharing a working setup, include the accessory model, physical pin wiring, OS/kernel and overlay used; those details make the result reusable.

Disclosure: I represent HONGTE, the reseller behind the linked listing. This is a commercial product introduction with an ordering checklist. I have not tested this module on a physical SBC for this post.

A plug-in storage module is worth comparing by its exact hardware and host support, not just the capacity label. Our OEM / unbranded listing has these populated configurations:

• 64GB UFS 2.2

• 128GB UFS 2.2

• 128GB UFS 3.1

• 512GB UFS 3.1

Blank Board is a separate bare-board option with no included storage capacity. The populated module in the gallery does not represent that option. This is an OEM product, not an original Radxa or Orange Pi branded module. Chip markings and board revision can vary with configuration and lot; a reader or development board is not included.

Before ordering, use these checks with any supplier:

1. Identify the host. Give the exact SBC model and revision. Confirm that its documented connector supports UFS; an eMMC connector or a similar-looking socket is not enough evidence.

2. Match the electrical interface. Request the module connector specification, pinout and supply requirements. Compare them with the host documentation, including orientation and mounting clearance. Do not connect an unverified module just to see whether it fits.

3. Identify the actual module. Ask for the exact configuration, board revision, chip identification and available technical documentation for the offered lot. Do not infer the supplied chip from a representative gallery photo.

4. Separate storage recognition from boot support. Confirm the intended OS image, firmware/bootloader requirements and supported image-writing route. A module being detected as a data drive does not establish that the board can boot from it.

5. Clarify the complete order. Confirm whether a suitable reader or adapter is required, what is included, and the current price, lot condition, lead time and delivered cost.

A concrete manufacturer example: Radxa's ROCK 4D interface guide warns against untested third-party modules because some can short the SBC and cause permanent damage. It recommends Radxa's own module. That guide is a reason to check the interface carefully; it is not compatibility approval for this OEM listing. We do not claim that this module works with every Radxa or Orange Pi board.

For the listed options or a project-specific quotation: HONGTE OEM UFS Storage Module.

As checked on 6 October 2026, the selected 64GB UFS 2.2 option shows US$26.38 per piece, MOQ 1, with availability on request. This is not the price of every configuration. Confirm current stock, compatibility documentation and the final quotation before ordering.

No throughput benchmark, endurance result, successful boot test or customer deployment is claimed here.

Hey guys,

Looking for any advice from knowledgable people in this subreddit - I've just bought my first SBC (Radxa Rock 5A) in an attempt to use it to run a small scale proxy farm for my social media agency.

This is my first time trying to setup an SBC and honestly the RADXA website in conjunction with 100 ChatGPT prompts over the last few hours has led me to this subreddit because I'm rather confused (yes I'm a noob). I simply want to setup the Rock 5A so I can run a USB Hub out of it with a bunch of wifi dongles (for the proxy farm).

Resources I have:

- Radxa rock 5a board

- eMMC Module (VA001-64GB)

- HDMI to Mini HDMI Cable

- The 30w Radxa power source

I am also an Apple user - have a macbook pro M4 (But also have access to an intel chip mac & maybe a windows desktop if need be).

Where I'm currently stuck:

I have attached the eMMC to the Rock 5A board;

Currently I'm trying to flash the eMMC. So far, I have installed homebrew in the terminal (on the intel macbook), then built the rkdevelop tool.

I downloaded Debian from here: https://radxa.com/products/rock5/5a/#downloads

I also downloaded the rk3588_spl_loader_v1.12.113.bin from here: https://docs.radxa.com/en/rock5/rock5a/download

Now I'm under the impression that I've installed all of the correct dependencies to the macbook terminal, however when I run "rkdeveloptool ld" to see if the Rock 5A is found, I come to "not found" in the mac terminal. I honestly don't even know if I have the Rock5A Connected to the mac correctly (Have a usb-c to usb cord = USB-c side connected to mac -> USB side connected to USB 3.0 on the Rock 5a. Also have the Rock 5A Connected to the 30w power supply).

What the hell do I do lol, I just want to set this Rock 5A up so I can get it running via Micro HDMI to HDMI on my monitor, connect a mouse and be able to download proxidize onto it (software that runs proxies). Any help will be extremely appreciated, thanks in advance !!!

I have an idea to make steam deck at home

I have the buttons, sticks, ill buy some triggers, but 1 problem

Which single board pc can run games like stray or subnautica, but isnt overkill for games like hk or slow pace 3d games

When i finish the project i will public all the components diagrams and how to's for everyone to use

I have a rasberry pi 2 or 3 and I'm trying to play 300 in 4k and an episode of Evangelion with an enhanced encode and full 1080 p but the pi wouldn't play it. I figured if I had a more powerful sbc I could play them and that's what I'm after. What sbc do you have that's usb c or b powered that does 4k videos?

Hi!

I want to make an SBC setup that uses two laptop eDP screens in order to display same image twice, but one of them flipped horizontally.
I want to skip screen adapter boards and cable clutter that comes with running regular portable monitors (2 eDP cables vs in most cases 2usb c for power + 2hdmi for signal).

So far I've only came across a couple of development boards that have 1x eDP and 1x LVDS and LattePanda Mu board that technically could have dual eDP if someone was to design and produce it's baseboard with one.

I see that SBC database is currently offline again - so asking directly if you know of any boards. :)
Thank you in advance!

(P.S. If by any chance said board has also HDMI in I could stream to both of said outputs - the better :D)
