SPECIFICATIONS

Description:

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 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.
