To program the Circuit Playground Express, you'll need to solder directly to the SWCLK and SWDIO pads on the back of the board.
After soldering, use a piece of tape or a dab of hot glue to hold the wires in place so they don't rip off of the pads.
Then, make the following connections between the Circuit Playground Express M0 and the SWD breakout:
- Circuit Playground Express SWDIO to Breakout SWIO
- Circuit Playground Express SWCLK to Breakout CLK
- Circuit Playground Express VOut to Breakout VRef
- Circuit Playground Express GND to Breakout GND
You can use breadboard-friendly Alligator clips to attach the Circuit Playground Express VOut and GND pins to the breakout.
You must also plug in a USB cable to the Circuit Playground Express to power it during progamming
