Pro Micro ATmega32U4 5V/16MHz Module Board, Replace with ATmega328 Pro Mini Compatible with Arduino with 2 Row Pin Header
Payment Methods:
Description
- ATmega32U4 microcontroller: 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.
- The acceptable voltage range is 5 to 9 V.
- On-Board micro-USB connector for programming; 4 x 10-bit ADC pins; 12 x Digital I/Os
- 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.
- 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.
