Arduino Pro Micro 5V/16MHz Atmega32U4-MU Board with Micro USB

Description

Arduino Pro Micro 5V/16MHz Atmega32U4-MU: Compact and Efficient Development Board with Micro USB Interface The Arduino Pro Micro Atmega32u4 is a small, breadboard-friendly microcontroller board. It has an operating voltage of 5V and a clock speed of 16 MHz, making it suitable for a wide range of applications. The ATmega32U4 microcontroller has 32KB of flash memory, 2.5KB of SRAM, and 1KB of EEPROM, and features built-in USB support, which eliminates the need for a separate USB-to-serial converter. The Pro Micro is commonly used for DIY electronics projects, hobbyist inventions, and educational purposes, and is ideal for projects that require a compact and low-cost microcontroller board. There is a voltage regulator on board which can accept a power supply of 6-9VDC (max. 10V). Make sure to connect the input voltage to the RAW pin and not VCC (5V). A pair of pin headers are included (require soldering). Features ATmega32U4-MU running at 5V/16MHz Supported under Arduino IDE v1.0.1 and above On-Board micro-USB connector for programming 9x 10-bit ADC pins 12x Digital I/O (5 are PWM capable) Rx and Tx Hardware Serial Connections Specifications Specification Details Microcontroller Atmega32U4-MU Operating Voltage 5V Clock Speed 16 MHz Digital I/O Pins 12 Pins (5 PWM capable) Analog Inputs 9 Pins UART (Serial) 1 (TX/RX) PWM Pins 5 Pins Flash Memory 32 kB SRAM 2.5 kB EEPROM 1 kB USB Interface Micro USB Power Input (via USB) 5V Power Input (Vin) 7-10V (external power supply) PINOUT Applications Ideal for creating compact embedded systems like sensors, wearable devices, and control systems. Perfect for rapid prototyping with minimal space and power requirements. Can be used to build custom keyboards, mice, or other USB devices, thanks to its USB capabilities. Used in IoT applications where a small, low-power board is required for communication and sensor data collection. Excellent for small robots or automated systems requiring precise control and small form factor.
