CH32V003 dev/breakout boards

Some kicad files for CH32V003 breakout boards

USB dev board

This is a simple and tiny USB dev board for the CH32V003 using CNLohr's ch32v003fun and rv003usb.

2 layer board, 0.8mm thickness.

The 1.5K resistor can be connected either to D5 or to VDD (not both). The series resistors on the underside are optional, cut the traces under them if you want to fit them.

Dual dev board

This board has a dual footprint to support both the TSSOP and QFN packages.

DIP outline breakout board

This design squeezes all the pins of the QFN chip into the format of a DIP package, useful for breadboarding. The three pins for the programming header are down the middle at the top.
