Pro Micro 3.3V 8MHz

This Pro Micro 3.3V is based on the open source design of the Arduino Micro and is largely compatible with the SparkFun Pro Micro 3.3V, making it both hardware and software compatible with the Arduino ecosystem. The Pro Micro 3.3V is a very compact board, with an ATmega32U4 microcontroller. For example, you can use it as a USB input device (e.g. keyboard and mouse), partly due to its dimensions, the Pro Micro is ideal for this.

See the following page for more information: Pro Micro

If the board registers on the computer as a "Pro Micro" then you still need to download the Board Definitions from Sparkfun for the Arduino IDE: Github sparkfun/Arduino_Boards
You can then select the corresponding type in the Arduino IDE.

Package contents:

• 1x Pro Micro 3.3V 8MHz
• 2x Pin headers

Note: The voltage regulator on these Pro Micro compatible boards can only handle a voltage up to 9V DC on the Vin/RAW pin, while the original boards can handle up to 12V DC. A voltage above 9V DC will cause the voltage regulator to overheat or malfunction.
