Pro Micro ATmega32U4 5V 16MHz Replace ATmega328 For Arduino TYPE-C With 2 Row Pin Header For Leonardo Mini Usb Interface Pro ATMEGA32U4 runs at 5V/16MHz Support Arduino IDE V1.0.1 Micro-usb interface programming on the board Four 10-bit ADC pins 12 digital I/O (5 PWM capability) Rx and Tx hardware are connected in serial This little board does all the neat adjacent Arduino tricks: 4-channel 10-bit ADC 5PWM pins, 12 Digital IO and hardware serial connections to Rx and Tx you're familiar with. Running at 16MHz and 5V. There is a voltage regulator on board, so it can accept voltage up to 12VDC. If you are supplying unstable power strips, be sure to connect to the "RAW" not VCC pins. This latest version fixes the silk bug so that pin 14 is correctly marked. We have also added a PTC fuse and diode to protect the power circuit and correct the RX and TX LED circuits
