Arduino Mega 2560 Pro Compatible Board with CH340 USB
The Arduino Mega 2560 Pro is a compact version of the Arduino Mega 2560, built around the ATmega2560 with 70 digital I/O pins, 16 PWM outputs, and 16 analog inputs — all in a smaller footprint than the standard Mega. Uses the CH340 USB-to-serial chip for programming via Micro USB. Fully compatible with the Arduino IDE and all Mega 2560 libraries and shields.
