  • It should be noted that the Arduino board used with this shield needs to supply 3.3V ! If you use it with a 5V 16Mhz Pro board it will be powering the MPR121 IC at 5V since what would be the 3.3V pin is tied to 5V instead! The MPR121 IC gets VERY hot. I don’t know if mine is permanently damaged or not.

No public wish lists :(
