Microcontrollers

Hi everyone, I would like to learn to program and built project using MicroControllers I'm a Python dev. Therefore I would like to use it to program those. But I've no idea where to start.. - For the hardware: - What will be the best Raspberry Pi or Arduino ?\ I know they are not the same thing but could tell me in which situation you use more one than the other ? Or do you use something else ? - Software - I've already my IDE [VisualCodium ](https://vscodium.com)\ What is **MicroPython** Vs **CircuitPython** ? If you have any resources I'm all eras. Thanks.

I have a design that includes an ATTINY424 doing simple logic functions / I2C monitoring. From my understanding UPDI is a half-duplex UART. For simple factory programming (no verification or debugging needed), do I need the RX side of the UART or can I just bit bang the programming sequence through a single open-drain I/O of another processor and ignore all responses? (Using an external FET to protect the processor from the possible 12V pulse of an external POD if I decide to use one at some time) Does anyone have experience with that? Verification is not required since the functionality of the ATTINY will be fully covered by the HW test.

So many different Arduinos. Which one do you use? What do you do with it?

The single core ESP32-C3 is a reduced ESP32 intended to replace the ESP8266.

A very handy pinout for the ESP32. Both the chip and the dev board. It has a handy chart to help you select pins.
