Description

Pro Micro similar to the Micro version, is based on the Leonardo module. The system is characterized by small size: 33 x 18 mm. It uses the Atmega32U4 microcontroller from AVR family. It is equipped with 20 digital inputs/outputs, 5 of them can be used as PWM outputs and 12 as analog inputs. The system works with voltages of 5V, it works with a clock signal with a frequency of 16 MHz.

 

Pro micro 5V/16MHz - SparkFun Arduino   

Unlike the Arduino Micro, it does not have connectors and reset button. The user decides which leads you will be needed, so the board can maintain its small size.

 

Attention!

Before connecting, read the installation guide.

 

Power

The module can be powered via micro USB cable and the external device, for example, the AC adapter, the battery or the rechargeable battery. If a supply voltage is higher than 5 V, it must be connected to the RAW lead which is connected to the stabilizer. VCC is directly connected to the pins of the microcontroller, connection of the voltage above 5 V may permanently damage the chip.

 

Inputs/outputs

Pro Micro has 20 digital outputs input/output (I/O). Each pin allows for current consumption with a maximum voltage of 40mA, which allows direct connection of LEDs with the resistors and controlling other chips. In addition to standard I/O some of the leads also have special functions.

 

Programming

Creating and downloading software is allowed by the free environment supplied by the manufacturer. Implemented bootloader allows you to send the program directly via USB cable. A detailed description can be found in the instructions supplied by SparkFun.
