Hello is the is MCU (STM32?) on the PCB “Grove-Base-Hat-for-Raspberry-Pi-Zero” allready programmed at PCB-delivery so that you could read analog Values/temperature Sensors(DS18B20) or ambient Sensors (I2C) like BME680 with the raspberry… or is it neccacary to programm the STM32 first?
Hey
The MCU is already programmed. You can find a tutorial on how to setup your raspberry pi with this hat here:

Let me know how that went
