If you need a tiny, low-cost microcontroller board with ultra-low power drain to embed in a project, Raspberry Pi Pico is ideal. It comes in several flavours, depending on how much processing power you need and whether you require wireless connectivity. All models feature a couple of bonus features: analogue inputs and PIO (programmable input/output) state machines that can handle some tasks in the background.
