  1. Brilliant little Arduino

    Posted by on

    Really small but so easy to use. Programable and powered via USB and all the usual Arduino/ATmega goodness.

    The first thing I do is solder on some header pins - makes it easy to use with a breadboard. In the final project I plug the mini / micro into a DIL socket - in case it blows up and needs replacing. (It would be really nice if these came with 24-pin DIL sockets - as they can be a pain to find!

  2. It's just like a baby arduino

    Posted by on

    This board is ideal for embedding into those projects where you still need to update the firmware or need serial over USB communication, a nice small form factor board, ready for those 'stand alone' projects, but still good for prototyping on a breadboard.

 Product Description

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: 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.

Dimensions: 1.3x0.7"
