Specification: Origin: Mainland China Type: Module Condition: New 1. Microcontroller: ATmega32U4 2. Operating voltage: 5V 3. Input Voltage: DC6-16V 4. Flash:32 KB 5. SRAM:2.5 KB 6. EEPROM:1 KB 7. Clock Speed:16MHz 8. Size:35*18*5mm/1.37*0.7*0.2in Product Overview: The Pro Micro is similar to the Pro Mini except that it is equipped with an ATmega.32U4. USB connectivity is added to the board due to the USB transceiver inside the ATmega32U4 chip: it has a 9-channel, 10-bit ADC, 5 pulse-width modulation pins, 12 DI0s, and hardware serial connections to RX and TX. It also has a voltage regulator, so it can accept up to 12 volts DC. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
