Description
Pro Micro similar to the Micro version, isbased on theLeonardo 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.
Unlike theArduino 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, readthe 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 havespecial functions.
Programming
Creating and downloading software is allowed by the free environmentsupplied by the manufacturer. Implemented bootloader allows you to send the program directly viaUSB cable. A detailed description can be found inthe instructionssupplied by SparkFun.
