I am trying to use the Adafruit MPR121 (the blue one without connectors) with the Sparkfun SAMD51 thing plus.
First off, is this even supported/possible, and if so, to what ports do I connect SDL and SCL?
For a regular Arduino UNO, the documentation specifies A4 and A5. Is this also the case for the SAMD51?
I would really like to change A4 and A5 to something like A0 and A1, since I already use the other two pins.

The MPR121 uses I2C, so should be possible. As long as the Sparkfun SAMD51 Thing supports use with the Adafruit library. You'd just connect SDA to SDA and SCL to SCL (basic I2C connections).

Hello,
Can we change the sensitivity of MPR121 TOUCH SENSOR by hardware or command.
