This product is fully compatible with Raspberry Pi 4 (1GB, 2GB,4GB) and hopes you enjoy hacking with Pi 4 and all of other Pi 4 accessories.
Because ST32 series chips are out of stock globally, prices have increased several times and there is no clear delivery date. We have no choice but to switch to the MM32 chip. The specific replacement models are as follows: STM32F030F4P6TR is replaced by MM32F031F6P6. After the chip is replaced, the product functions, features, usage methods and codes remain unchanged. It should be noted that the firmware version has changed, and the factory firmware has been adjusted according to different chips. If you need to re-burn the firmware, please download the firmware corresponding to the chip.
ADC is a common accessory for Raspberry Pi. Nowadays many cheap MCUs has built-in ADC, so we make this 8-channel ADC based on STM32F030, which is a cost-effective, low-power ARM Cortex M0 MCU. We breakout 8 channels ADC from the MCU, and integrated 4 analog Grove connector so that you can also use analog Grove modules with it.
