Arduino Nano
The Arduino Nano is a compact board that trades a smaller size for fewer IO pins than the Arduino Mega boards. It is a great choice when space is at a premium.
Warning
Many lower-cost Nano boards, particularly those purchased from AliExpress, use the CH340G chip for serial communication to the PC. These chips are frequently counterfeit and require additional driver installation.
Purchasing an Arduino Nano from the MobiFlight Shop ensures you will get a board with genuine chips.
Specifications
- 12 digital IO pins, 6 with PWM support (pins D0 and D1 cannot be used).
- 8 analog inputs (can be used as digital inputs, except for A6 and A7).

Pinout
Note
Pins D0 and D1 are not available for use, as they are reserved for USB serial communication.
Pins A6 and A7 are only available for analog input, they cannot be used as digital inputs.
