Arduino Mega 2560 R3 Compatible Board with CH340 USB
The Arduino Mega 2560 R3 compatible board with CH340 delivers the full power of the ATmega2560 — 54 digital I/O pins, 16 PWM outputs, 16 analog inputs, and 4 hardware UART ports — at a lower cost using the CH340 USB-to-serial chip. Fully compatible with the Arduino IDE and all Mega 2560 libraries, shields, and RAMPS boards after installing the CH340 driver.
Key Specifications
- MCU: ATmega2560 | Clock: 16MHz
- Flash: 256KB | SRAM: 8KB | EEPROM: 4KB
- Digital I/O: 54 pins | PWM: 15 channels | Analog in: 16 channels
- UART: 4 hardware serial ports | Interfaces: SPI / I2C
- USB: USB-B (CH340) | IDE: Arduino IDE compatible
- Compliance: RoHS compliant
Why Choose This?
- ✅ Cost-effective CH340 — same ATmega2560 performance at lower price
- ✅ 54 digital I/O + 16 analog — ideal for complex multi-sensor projects
- ✅ 4 hardware UARTs — connect multiple serial peripherals simultaneously
- ✅ RAMPS shield compatible — standard 3D printer control platform
Typical Applications
- 3D printer control (RAMPS 1.4/1.6 compatible)
- CNC machine and multi-axis motion control
- Large robotics projects with many sensors and actuators
- Complex automation with multiple serial peripherals
