Key Features
- Native USB Communication: The ATmega32U4 handles USB directly on-chip, allowing the board to appear as a mouse, keyboard, joystick, or any custom HID device to a connected computer - no FTDI chip or external programmer required.
- Ultra-Compact Form Factor: At just 33 mm x 18 mm, this is one of the smallest Arduino-compatible boards available, making it perfect for wearables, embedded enclosures, and projects where every millimeter counts.
- Breadboard-Friendly Design: Castellated edge pins and standard 0.1" header spacing allow direct soldering or breadboard insertion for rapid prototyping.
- 18 Digital I/O Pins: Generous GPIO count with 5 PWM-capable pins for motor control, LED dimming, and analog signal generation.
- 9 Analog Inputs: More analog channels than most compact boards, enabling multi-sensor data acquisition without external multiplexers.
- Full Arduino IDE Compatibility: Program using the familiar Arduino IDE by selecting "Arduino Leonardo" or "SparkFun Pro Micro" from the board manager. Thousands of existing libraries work out of the box.
- QMK Firmware Support: The go-to board for custom mechanical keyboard builds - fully supported by QMK, VIA, and other keyboard firmware frameworks.
- Onboard Voltage Regulator: Accepts power via Micro-USB (5V) or the RAW pin (up to 12V), with an onboard regulator providing stable voltage to the microcontroller.
- TX/RX LEDs and Power LED: Onboard indicator LEDs for serial activity and power status, simplifying debugging.
- SPI and I2C Support: Connect sensors, displays, SD card modules, and other peripherals through standard communication protocols.
Why Choose This Arduino Pro Micro Compatible Board?
- Authentic Quality Components: Built with genuine ATmega32U4 chips and quality PCB manufacturing for reliable, long-term performance sourced from trusted suppliers.
- Best Value for USB Projects: Get native USB HID capability at a fraction of the cost of original boards without sacrificing functionality or compatibility.
- Proven Community Support: Millions of tutorials, code examples, and forum discussions available - one of the most well-documented microcontroller platforms in existence.
- 1-5 days shipping from Bengaluru: Ships from our Bengaluru warehouse with fast delivery across India and same-day dispatch for local orders.
- Expert Technical Support: Our engineering team provides hands-on guidance for your projects via email and WhatsApp, 24/7.
- Ideal for Production & Prototyping: Whether you are building one prototype or deploying hundreds of units, this board delivers consistent performance.
Project Ideas
- Custom Mechanical Keyboard: The most popular board for DIY keyboard builds. Use QMK or VIA firmware to create fully programmable keyboards with custom layouts, macros, RGB lighting, and multiple layers. Build split keyboards, macro pads
