Introducing the Pro Micro, a compact marvel that shares similarities with the Pro Mini, but boasts an ATmega32U4 on board. The inclusion of the USB transceiver within the 32U4 enables seamless USB connectivity without the need for cumbersome external interfaces.

Packed with all the ingenious Arduino features you know and love, this diminutive board offers 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs, and hardware serial connections for Rx and Tx. Operating at a swift 16MHz and 5V, the Pro Micro resembles your favourite Arduino-compatible boards, yet its petite size makes it incredibly versatile, fitting into almost any project. Equipped with a voltage regulator, it can handle power inputs up to 12VDC. If providing unregulated power, ensure a connection to the “RAW” pin instead of VCC.

This latest iteration rectifies the silk error present in the previous version by accurately labelling pin 14. Additionally, we’ve incorporated a PTC fuse and diode protection into the power circuit, addressing concerns related to RX and TX LED circuits.

Key Features:

  • ATmega32U4 running at 5V/16MHz or 3V/8MHz
  • Arduino IDE v1.0.1 compatibility
  • On-board micro-USB connector for both programming and non-USB applications
  • 4 x 10-bit ADC pins
  • 12 x Digital I/Os, with 5 PWM-capable pins
  • Rx and Tx hardware serial connections

Compact and measuring only 3.3 x 1.8 cm, the Pro Micro is your go-to solution for a wide array of projects. Upgrade your creations with the power and flexibility of this versatile microcontroller board.
