Arduino Mega Board 2560 R3-Compatible gives your projects more pins, memory, and serial ports without changing your workflow. With the ATmega2560 @ 16 MHz, 54 digital I/O (15 PWM), 16 analog inputs, and 4 hardware UARTs, it’s a favorite for robots, CNC/3D-printer control, dashboards, and classroom labs in the Philippines. The R3 layout keeps it friendly with most Arduino shields, sensors, and displays.
Go Big on I/O — 54 Pins, 4 UARTs, Mega-Sized Projects
- Massive expansion: 54 digital pins, 16 analog, 15 PWM for complex control panels and bots.
- Multi-serial ready: 4 UARTs let you run GPS, GSM, Bluetooth, and a PC console simultaneously.
- Memory for larger sketches: 256 KB Flash and 8 KB SRAM handle libraries, buffers, and UIs.
- Shield & library friendly: R3 footprint, 5 V logic, and broad Arduino ecosystem support.
What you can build
- Robotics: 4WD/6WD platforms with multiple motor drivers, IMU, ToF, and encoders
- CNC/3D printing: motion control with RAMPS-style shields, endstops, heaters, fans
- Data acquisition: multi-sensor logging via RTC + microSD shields
- Interface hubs: keypads, relays, stepper drivers, large TFTs and LED matrices
Starter bundles (quick picks)

Pinout & power notes
- SPI: Use the 6-pin ICSP header for SPI to ensure shield compatibility (don’t rely on pins 50–53).
- 5 V logic: If a module is 3.3 V-only, add a logic level converter.
- Serial devices: Put GPS/GSM/Bluetooth on Serial1–3 and keep Serial free for debugging.
- Power budget: Servos/steppers need an external supply; don’t power motors from the board’s 5 V rail.
What’s in the box
- Mega 2560 R3-compatible board (USB cable not included unless stated in variants)
- Pre-soldered headers (typical for this board class)
FAQs – Mega 2560 R3-Compatible (Philippines)
Will my UNO shields work?
Yes—most UNO R3 shields are compatible. For SPI shields, use the ICSP header; adjust chip-select pins if stacking multiple shields.
Which cable and drivers do I need?
Use a USB-B cable. If your PC can’t detect the board, install the correct USB driver (e.g., CH340 or CP2102), depending on the batch.
How is the Mega different from the UNO?
More I/O (54 vs 14), more memory (256 KB vs 32 KB), and 4 UARTs instead of 1—ideal for larger projects and multiple peripherals.
Do you ship nationwide and support school/corporate orders?
Yes. We ship nationwide across the Philippines via trusted couriers and can prepare classroom bundles and bulk quotations on request.
