Arduino Mega 2560 R3 Compatible Board with CH340 USB

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
