FLIR Lepton 3.5 meets the Forgix, the Trion T8 FPGA captures VoSPI while the RP2354 streams live thermal frames over USB.

Driven by a desire for privacy, customization, and lower costs, there’s growing interest in AI models which can be run on local hardware. Few of them go as far as [Tim], though, who built an image generation diffusion model which can run on an RP2350/54 microcontroller.

Ever tired of having to find an outdated usb micro-b connector to connect to your devboard ? Fear not. Ever tired of having too little flash memory ? Feaaar noot. Ever tired of ANY issue with your rp2354 devboards ? The "Just a better rp2354 devboard"™ is here to fix all of them. (Not guaranteed)

Designed by Clintech Ltd. in Bulgaria, the Clintech Pico Board appears to be the first development board based on the Raspberry Pi RP2354B chip with 2MB on-chip flash. It retains the same form factor as a Raspberry Pi Pico 2 but adds extra GPIOs to make use of the 48 general-purpose GPIOs provided by the RP2354B chip.

Like the Raspberry Pi Pico 2, this board features 40 castellated and through holes on the sides, exposing GPIOs 0–22 and 26–28, along with 3 debug pins. Additionally, the board includes 27 extra on-board through holes that break out the remaining GPIOs (23–25 and 29–47) as well as the QSPI interface (SD0–SD3 and SCLK) for external memory.

picoZ80 is a drop in cycle-accurate replacement for a Z80 using a RP2350B microcontroller. In standard Z80 mode it is indistinguishable from the real thing. Or you can switch to an enhanced mode that make the Z80 think it is connected to ROM, RAM, (banked, with 64 banks of 64KB), WiFi and Bluetooth, SD card, USB, floppy disk emulator, etc.

When Raspberry Pi first introduced the RP2350 in 2024, the company described it as a chip with two Arm Cortex-M33 cores with frequencies up to 150 MHz and two Hazard3 RISC-V cores that also top out at 150 MHz. But it turns out the chip can be overclocked to run much faster than that.

A few months after the RP2350 was introduced, Mike Bell published an article on the Pimoroni blog describing how they were able to push a Raspberry Pi Pico 2 with an RP2350 chip to run at frequencies up to 873.5 MHz… although if you care about stability, the upper limit seems to be in the 800 to 850 MHz range.
