A welcome upgrade to the Raspberry Pi Pico RP2040 board. Seems a bit on the expensive side but when you add the extras of the soldered headers, the LiPo charging and the reset button (useful when developing micropython) the prices are similar. Have tested the LiPo charging and its even bought a dead cell back to life. Would like to find out how to access the charging circuitry via code (if this is possible) to provide a charging/charged indicator as the board only has a single led, which is user definable.
