This tiny little board does all of the 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 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. Features: ATMega 32U4 running at 5V/16MHz On-Board USB connector for programming directly with popular IDEs. No need for separate flashing hardware! 4 x 10-bit ADC pins 12 x Digital I/Os (5 are PWM capable) Rx and Tx Hardware Serial Connections Package: 1 X New Pro Micro ATmega32U4 5V 16MHz Module |
