Pro Micro 5V 16M Mini Leonardo Microcontroller Development Board For ArduinoDescription:This microcontroller development board has 4 channel 10 bit ADC、 5 PWM pins、 12 DIO、 and a hardware serial connection Rx and Tx you are familiar with. Running on 16MHz and 5V、 this board will remind you a lot of other Arduino compatible boards that you like. There is a voltage regulator on board、 so it can accept up to 12V DC. If you are supplying an unstable power supply board、 be sure to connect to the !#!amp!*!quot;RAW!#!amp!*!quot; not on the VCC pin. We have also added a PTC fuse and diode protection to the power circuit and to correct the RX and LED TX circuits.Feature:- 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 connectionPackage included:1 x Module
