Notes:
- 1
- Without included optional headers. This measurement includes the USB Micro-B connector, which extends 0.05″ past the edge of the PCB.
- 2
- Without included optional headers.
- 3
- 8 KB of the MCU's 32 KB of flash memory is used by the pre-installed USB bootloader. All 32 KB is available if you use an external programmer and erase the bootloader.
- 4
- All 30 can be used as digital I/O, 25 can be used as analog inputs, and one can be an analog output. 28 of the 30 are available along the sides for use in a breadboard.
- 5
- For light loads. The regulator's dropout voltage increases approximately linearly with the load, from a few millivolts at no load up to around 0.6 V at 500 mA.
- 6
- On BAT+.
