The esp32 devboards are magnificent, as it is so easy to replace the need for official Arduino boards - Arduino compatible - platformIO supported - very cheap - they are usually tiny - great wifi and Bluetooth - gpio pins for the different protocols (i2c etc) - easy to power (tolerance and options in usb and pins) - lots of exciting new models and active development like the esp32c3, the D1 minis and different models with integrated oleds are cool - community resources. there are massive amount of blogpost and YouTube videos for esp32 (and Arduino in general) cons are few; - 3.3v signal is a hassle quite often in practise - the amount of different esp32 devboards models can get confusing - the pins are sometimes shared-purpose and it's not always clear which you can use - China. Both practical for delivery time, and politically
