On-Board micro-USB connector for programmingįor more information, please follow the link to the official Arduino Pro Micro project page: klick here. The Pro Micro is an Arduino-compatible microcontroller development board based on the ATmega32U4 IC.Supported under Arduino IDE v1.0.1 and above.A pair of pin headers are included, as shown in the picture. It comes with the Atmel Atmega32u4 MCU and runs with 16MHz. Nevertheless it still can be put in a bootloader reset mode by wiring twice the RST (reset) and GND (ground) pins use for this a piece of a wire or create a temporary button. The Pro Micro Arduino compatible board is originally developed as open hardware by the company Sparkfun. The process of resetting of the Arduino Pro Micro is a bit tricky as it doesn’t have a hardware RESET button. This is simple half duplex radio communication device built with CC1101 module and Arduino Pro Micro (3. The USB transceiver is inside the 32U4, adding USB connectivity on-board without external. Make sure to connect the input voltage to the RAW pin and not VCC (5V). The Pro Micro is a microcontroller with an ATMega32U4 IC on board. There is a voltage regulator on board which can accept a power supply of 6-9VDC (max. Running at 16MHz and 5V, this board will remind you a lot of your other favourite Arduino-compatible boards but this little guy can go just about anywhere. Every time you upload an Arduino sketch, the vendor and product names/IDs are also uploaded to the device. The tiny little Pro Micro Atmega32u4 board does all of the Arduino tricks that you’re familiar with:ĩ channels of 10-bit ADC, 5 PWM pins, 12 digital I/O as well as hardware serial connections Rx and Tx. SparkFun Pro Micro Product name To see the USB devices in Windows, press the Win and search for the Device Manager in the Start Menu. With dimensions of 34 x 18 mm is Pro Micro Atmega32u4 only 3/4 of the size of an Arduino Nano, and only half of its height. Together with the micro USB port, Pro Micro Atmega32u4 is only 4 mm high.
