About this part
A compact Arduino-compatible board built on the ATmega32U4, running at 5V and 16MHz and programmed from the Arduino IDE. It packs digital, PWM, analog and hardware serial pins into a small footprint for builds where a full-size board won't fit.
- Chip: ATmega32U4 at 5V and 16MHz
- I/O: 12 digital pins, 5 with PWM, plus 4 channels of 10-bit analog input
- Serial: hardware RX and TX
- Power: onboard regulator accepts up to 12V DC on the RAW pin, with a PTC fuse and diode protection
- USB: Micro USB or USB Type-C, your choice
Feed an unregulated supply into RAW, not VCC, so the onboard regulator can do its job.

Characteristic: ATMEGA32U4 running in 5V/16MHz Supported by V1.0.1 IDE Micro USB interface programming on the board of directors 10 4 bit ADC pins 12 digital I / O (5 PWM capability) Rx and Tx hardware serial connection Explain: This little board all the adjacent neat skill: 4 Channel 10 bit ADC, five PWM pin, 12 DIO and hardware serial connection RX and TX you are familiar with. Running on 16MHz and 5V, this committee will remind you of a lot of other compatible boards that you like, but this little guy can go anywhere. There is a voltage regulator on board, so it can accept up to 12VDC. If you are supplying an unstable power supply board, be sure to connect to the "RAW" not on the VCC pin. This latest version of the modified silk error, so pin 14 is the correct mark. We have also added a PTC fuse and diode protection to the power circuit and to correct the RX and LED TX circuits.
