• Compatibility with standard USB A-to-B (printer-style) cables

USB A-to-B cable typically included

4. CH340 USB-to-Serial Converter

Uses the widely supported CH340 interface chip, providing:

• Stable USB communication

• Easy driver installation

• Reliable uploads through Arduino IDE

• Compatibility with Windows, macOS, and Linux

5. Expanded Program & Data Memory

• 256 KB Flash memory (≈248 KB available for sketches)

• 8 KB SRAM for variables and buffers

• 4 KB EEPROM for permanent data storage

Ideal for large programs, multiple libraries, configuration storage, and data logging.

6. Multiple Power Input Options

• USB 5V power

• DC barrel jack input (7–12V recommended)

• Onboard 5V and 3.3V voltage regulators

Supports external power supplies, battery packs, and standalone operation.

7. Massive I/O Capability (Mega Advantage)

A total of 86 I/O pins, including:

• 54 Digital I/O pins (15 PWM outputs)

• 16 Analog inputs (A0–A15)

• 4 UART serial ports (Serial0–Serial3)

• I²C (SDA 20, SCL 21)

• SPI via ICSP & D50–D53

Perfect for projects requiring many sensors, motors, displays, or communication devices.

8. Standard Arduino Mega Form Factor

Designed with the Mega 2560 R3 footprint, compatible with:

• Mega-specific shields

• RAMPS boards (3D printers)

• CNC shields

• Relay & expansion boards

• Industrial and automation shields

9. Works seamlessly with:

• Arduino IDE (Windows / macOS / Linux)

• PlatformIO

• All Arduino Mega 2560 libraries

• Mega-compatible shields and modules

10. Wide Range of Applications

Ideal for:

• Robotics & multi-axis motor control

• 3D printers & CNC machines

• Industrial automation

• Smart home controllers

• Large sensor networks

• Data logging systems

• Advanced IoT prototypes

• STEM education & engineering labs

Note: This is an Mega 2560 compatible board. It is not an official Arduino-branded product, but is fully compatible with the Arduino IDE, libraries, and Mega 2560 shields.
