Trinket M0 Accessing the SWCLK and SWDIO pins
Is there any way to use the SWCLK and SWDIO pins as standard IO in Circuitpython? (Neopixel data pin actually.) The pins don't seem to be defined in the board, microcontroller, or microcontroller.pin modules. I'd prefer two FSR's to one, which leaves me 1 pin short. I don't want to try to solder a wire to the red LED unless I absolutely have to. TIA

Re: Trinket M0 Accessing the SWCLK and SWDIO pins
For anyone reading this later, I never figured out how to use these pins. However, there is a via between pin 13 and the resistor for the red LED that is right next to the resistor. If you have enough magnification, you can remove the resistor and use an exacto knife to scrap off the black solder resist from the via. This gives you enough contact area to solder a 30AWG wire to.

The QTPY is an option you could make use of.https://www.adafruit.com/?q=qtpy&sort=BestMatch
