Arduino Pro Micro ATmega32U4 Description:
Pro Micro ATmega32U4 5V/16MHz Module Board with 2 Row pin Header Replace with ATmega328 Pro Mini for Arduino. Note: When you open the IDE software, pls go to the Tool and choose the board “Leonardo”
The Micro is a microcontroller board based on the ATmega32U4 (datasheet), developed in conjunction with Adafruit.
- 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.
We have tech support for after-sale.
- If it can’t be recognized by your computer when you use it, please change another USB cable or computers to test, if still no any update, may you need to install a driver ,
- we made a detail tutorial, you can visit: https://youtu.be/9k5mk-FHF24 if still not solved it, please tell us. We can definitely help you to fix the problem .
- 1. The Pro Micro is similar to the Pro mini except with a 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
2. This tiny little board does all of the neat-o 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 pro-compatible boards but this little guy can go just about anywhere.
- If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin on not VCC.
3. 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.

Our Smallest pro-Compatible Board Yet
Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.
