Pro Micro 3.3V Development board Micro USB For Arduino Leonardo ATMega32U4 Controller Replace ATmega328 Blue

Highlights

• Power Support This tiny little board does all of the things for Arduino tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins.
• Connect with 12 DIOs as well as hardware serial connections Rx and Tx.
• Running and Voltage Running at 8MHz and 3.3V, this board will remind you a lot of your other favorite for Arduino-compatible boards. There is a voltage regulator on board so it can accept voltage up to 12VDC.
• Safe Protection This latest revision corrects the silk error from the last version of the board sothat 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.
• Use it in Suitable for DIY enthusiasts to developing, learning and testing Code and using school textbooks.
