Micro ATmega32U4 5V 16MHz, Compatible for Arduino. ATmega 32U4 Running at 5V/16MHZ, Supported Under IDE V1.0.1, On-Board Micro USB Connector for Programming, 4 X 10-Bit ADC Pins

Micro ATmega32U4 5V 16MHz Module


  • The pro micro is similar to the pro mini except with an ATMEGA32U4 on board.
  • The USB transceiver inside the 32U4 allows us to add
  • USB connectivity on-board and do away with bulky external USB interface.
  • This tiny little board does all of the neat tricks that you’re familiar with:
  • 4 Channels of 10-bit ADC, 5 PWM pins, 12 dios as well as
  • Hardware serial connections RX and TX. Running at 16MHZ and 5V,
  • This board will remind you a lot of your other favorite compatible boards but this little guy can go just about anywhere.
  • There is a voltage regulator on board so it can accept voltage up to 12VDC.
  • If you’re supplying unregulated power to the board, be sure to connect to the “RAW” PIN on not VCC.
  • This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled.
  • We’ve also added a ptc fuse and diode protection to the power circuit and corrected the RX AND TX LED circuit.
