Arduino-Compatible Mega 2560 R3 - ATmega2560 CH340G dfr0229 Onboard Microcontroller: ATmega32u4The Mega 2560 R3 (CH340G clone) is the high pin count Arduino board for projects that outgrow the UNO. Same form factor as the official Arduino MEGA, same ATmega2560 16AU processor, but uses a CH340G USB to serial chip instead of an ATmega16U2 which keeps the price under PHP 800 while staying 100% Arduino IDE compatible. Best for builds that need more I O, more memory, or multiple hardware serial ports: 3D printers (RAMPS Marlin), CNC controllers,
