Raspberry Pico-based 100-Msps logic analyzer
People sometimes dismiss the Pico in comparison to an ESP32 or other ESP-based devices (even the newer Pico W, which has wireless capabilities, with Bluetooth LE potentially added via software update in the future), but I've seen Picos running as N64 flash carts, logic analyzers, signal generators, etc. in places where formerly only more expensive FPGAs or low power ARM SoCs (not on the microcontroller level) were used before. It's not punching too much above it's weight, but the PIO does seem to be a very useful feature.I know there are still other advantages of the ESP32 (especially in some of the newer revisions, like upcoming Matter/Zigbee support built in), but I think some people are too quick to dismiss the Pico's RP2040 as overpriced compared to the alternatives.
