Go 1.19 started reformatting code in a way that makes it more obvious how it will be rendered on pkg.go.dev. It gets it almost right, but not entirely. Therefore, I had to modify some of the comments so that they are formatted correctly.

// This contains the pin mappings for the Arduino Nano RP2040 Connect board.

|
|
// Sometimes the board is not detected even when the board is connected to your computer.
|
|
// To solve this, place a jumper wire between the REC and GND pins, then connect the board to your computer.
