Pro Micro - 5V/16MHz

by Sparkfun

At SparkFun, they refuse to leave ‘good enough’ alone. That’s why they’re adding to their 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: 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 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 labeled. We’ve also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit.

The one-liner installer works well on a clean install of Retropie. The amp is just enough to drive a T1-2121SD

Upgraded my original Kickstarter Picade and needed this for Pi 4 compatibility. Works the charm- only wish is that audio was stereo. Other than that, it works well and was an easy upgrade! Recommended

Works perfect, very easy to setup, connecting all buttons, joystick and all has been as easy as it gets. Plus the on/off switch is a real treat compared to the old plug / unplug you're used to with the Raspberry Pi. Would recommend 100% !

This is a brilliant controller board for our arcade project, and makes it really easy to connect everything. We haven't tested it yet but it is a great board.

An excellent bit of kit! I paired it with RetroPie and my 1980s Competition Pro joystick to create my own little piece of 8-bit gaming heaven...

This is a great little board! I wanted to power a Pi and Pi Display in a SmartPi case with USB-C for a bit more power and this was available at an opportune time. The +/- are placed with just enough space to solder a right angle connector and feed wires through the case to the display. Still waiting to get hold of a PSU but this is working well off a bench supply. Software was easy to install, and the IO will come in handy for any controls I want to add to my project.

Bought this for an arcade project along with a Pi 3 A+. Easy way to provide on/off switch functionality, an audio amp with speaker output and any extra buttons needed.
