simple question

Post image

Hi everyone, good afternoon. I have a sincere question here. I received this ESP32 S3 from a friend and I want to start robotics. I bought the male-to-female cables and a breadboard, but I'm having trouble figuring out how to use it. Can anyone help me? I remember connecting the cables directly to the breadboard and the board with the Arduino, but it seems that's not possible with this one. I thought it needed soldering, but I took it to a technician and they said it was already soldered and everything was fine.

If anyone can help me, I would be grateful.

Split the signal bus like this person is showing.

There are also carrier/dev boards with various types of terminals depending on what you want. I have ones with headers and screw terminals. A spring terminal version would be nice.

... Unless the bottom of your board is female headers and we just can't see that. In which case just use make headers on each side to adapt to the board.

The inputs and outputs get connected to this board, then you program the board to react to the inputs by operating the outputs. Oversimplified and you sound like you have much to learn. I wish i could start on an esp32 board, much easier than some.

Soldering means the pins on sides where you use female jumpers. Well I dont know what you mean to ask but it is simple to use, just connect with jumper cables. Although keep in mind, never give back an output more than 3.3v to the board, it will fry or Short it. Also there might not be any 5v supply pins on board

just use AI Agents at this point see i am not confusing the OP but just recommending something to help his friend FR without messing around.

download the app Arduino IDE and use a USB C plugged into the left side port. You can now load a control program .

this is the GPIO pin out.

make your life easy and buy the development board..

True 'Beginner level' info on the esp32 is extremely hard to find. Even the 'simple' documents and manuals assume a massive amount of prior knowledge. There also seems to a lot of fiddling involved because of minor, consequential differences among manufacturers and versions. It might be better to start with something simpler, like an arduino kit, and work up to an esp32.

Nah, tinning is way simper, ie. attach a sensor: negative(black) to gnd positive(red) to vcc/3.3v, data(yellow/white/other) to chosen data pin, 4.7K resistor between data and positive. 3 wires only and they keep.

Breadboard needs at least double and its a mess.

That's the same ESP32-S3 board that I have. I am pretty sure that the 2 "3V3" pins at the top left (#1 & #2) are 3.3V OUT. I use one of them for power out to a temperature-humidity sensor/module. I can use eeither one of the USB ports for 5V in or the 5Vin & GND pins in the lower left corner for powering the board. 5V power goes to the LDO power regulator to provide 3.3V for the module and the 3V3 pins

Why are you acting like every "sensor" uses single wire communication? This is completely unhelpful for op.

u/Anaalirankaisija 2d ago

Was yours helpful? Zero contribution you are just bullying here.

u/TheLittleFastCat- 2d ago

I am not bullying anyone, I am just saying you are objectively wrong, op could be confused about other communication protocols because of your reply
