Pro Micro USB-C Controller (Black/Blue/Purple)

Pro Micro controller module with USB-C socket

Popular cheap microcontroller module based on Atmel ATmega32u4

• USB-C socket
• 5 V operating voltage
• 16 MHz clock
• 2.5 kB SRAM
• 32 kB flash
• Includes 2x 12 pin headers

Electrically and physically compatible with the standard Pro Micro with the following differences:

• Long side longer by 0.5 mm (black) / 2.5 mm (blue/purple)
• 1.3 mm (black) / 1.1 mm (blue/purple) thicker overall (due to the top-mounted USB-C socket)

The new black version is almost the same size as the original Pro Micro / Elite-C / nice!nano, however, some components are mounted on the bottom which is not completely flat.

Comes with modified Arduino Leonardo (Caterina) bootloader by SparkFun – reset twice quickly to get to the bootloader mode for 8 seconds.
