The LilyGo T-Pico 2350 is neat for a couple reasons:

* it has an RPi 2350 and an ESP32C6 on it
* It has a delightfully batshit usb connector where the usb-c orientation decides which CPU your USB connects to
* The C6 has built in jtag
* the 2350 doesn't have jtag but it does have a good bootloader
* it has a screen and some buttons and an sd card slot and a micro hdmi port
* it has some headers, and I think maybe some sensors?
