A dev board with an upgraded LDO compared to other traditional devboards, which will allow for using devices that need higher current draw.
I made this to allow for easier prototyping as it gives extra breathing space when prototyping with many components connected at once to a dev board.
RP2040 chip
29 GPIO pins
12Mhz Crystal
High current LDO
DO
