Frequently asked questions
How do I program it?
It is programmed through in-circuit serial programming (ICSP) using a PIC-compatible programmer such as PICkit, with Microchip's MPLAB X IDE. It is not programmed through the Arduino IDE.
Can it run from a 5 V supply?
Yes. Its operating range is 2.0 V to 5.5 V, so 5 V is within specification. As with any microcontroller, place a decoupling capacitor close to the VDD pin.
