Description
Arduino Pro Micro 5V 16M Mini Leonardo Micro Controller Development Module
There is a voltage regulator on board, so it can accept up to 12V DC.
The Micro is a microcontroller board based on the ATmega32U4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button.
It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.
The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
If you supply an unstable power supply board, be sure to connect to the “RAW”, not on the VCC pin. It has also added a PTC fuse and diode protection to the power circuit and corrected the RX and LED TX circuits.
Features :
- ATMEGA32U4 running in 5V / 16MHz
- Support Arduino IDE V1.0.1
- Micro USB interface programming on the board
- Four 10-bit ADC pin
- 12 digital I / O (5 PWM capability)
- Rx and Tx hardware serial connection.
