To comply with the USB-C specification and ensure the board draws power from modern USB-C to USB-C cables, the schematic includes two independent connected to the CC1 and CC2 pins. Without these resistors, smart chargers or host devices will view the board as an open circuit and refuse to supply 5V power. Impedance Matching and Data Lines ydrp2040 schematic
When designing with the YD-RP2040 schematic, keep these in mind: sm = rp2
