Here at SparkFun, we refuse to leave 'good enough' alone. That's why we're adding to our line-up of Arduino-compatible microcontrollers once more! 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-o Arduino tricks that you're familiar with: 9 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 favourite Arduino-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 labelled. We've also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit.
The classic 5V Arduino-compatible board, perfect for simple projects using standard 5V sensors and code. No FTDI Breakout required!
The low-voltage version of the classic board, designed for battery-powered projects or 3.3V sensors. No FTDI Breakout required!
A modernized version of the classic 5V board, upgraded with a robust USB-C connector and a Qwiic port for easy sensor connection.
An IoT flagship featuring WiFi and Bluetooth Low Energy (BLE) in the tiny Pro Micro footprint, ideal for connected projects.
