At the fundamental level, the ESP32 is the same as Arduino and RPi Pico boards: it’s a microcontroller that’s useful for any DIY project ... and you’ll have to program the device using ...

If you want to try a Scratch-inspired take on microcontroller programming, check out MicroBlocks. It will work with several common boards, including the micro:bit and the Raspberry Pi Pico.

For instance, making a board for an 18-pin PIC microcontroller into a single ... reset button, and programming header are also on the breakout board and will not have to be built in place.
