Keywish Expansion Board: Raspberry Pi 2B/3B/3B+/4/Zero Compatible Sensor Board, 5V 3A Support, 8-Channel ADC Reading with MCU Review

This Emakefun Micro Bitboard can be a challenge. This is a Chinese board and all the documentation I found is in Chinese but is available with English translation. It looks like it will break through the Raspberry Pi's signals and improve interaction with the Pi. I look forward to learning more about this fascinating supplement.

This board is great for experimenting with Raspberry Pi GPIO. This board shares the GPIO pins, making it easy to connect analog sensors to STM32 to read the analog signal and perform an ADC to send to the Raspberry Pi. 8 channels can be used on the board, which means that several analogue signals can be fed in at the same time. Great for prototyping or experimentation. No documentation was included, but it can be found by searching the board on Google. The online instructions will help you set…

An interesting board. It has its own ARM processor dedicated solely to using the sensors, leaving the RPi's processor time for other, more interesting things. This is STMicroelectronics STM32F030F4P6. There are no instructions on the board, but you can find them by searching Google for "emakefun readthedocs raspberrypi-sensor-board-master". The documentation states the following specifications: Features: Supports 8-channel ADC detection Built-in MCU Supports Raspberry Pi 2B/3B/3B+/4/Zero…
