I am unsure of how to fix this issue if you continue to use code that interferes with the CDC. Interrupts Atmega32u4's built in CDC driver for USB communication can have timing issues when messing with the watchdog timer, sleep modes, and timer interrupts. Timing Issues w/ USB Communication through CDC Not sure which Arduino or Arduino-compatible board is right for you? Check out our Arduino Buying Guide! We've also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit. This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC. There is a voltage regulator on board so it can accept voltage up to 12VDC. 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. This tiny little board does all of the neat-o Arduino tricks that you're familiar with: 9 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface. 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. Here at SparkFun, we refuse to leave 'good enough' alone.
