DFRduino Mega2560

DFRduino Mega2560 is an enhanced ATmega2560-based microcontroller. It improves the VIN power supply circuit by replacing the LDO with a DC-DC circuit, addressing overheating issues and offering a wider input voltage range. DFRduino Mega2560 can operate steadily with a 3.7V lithium battery. It features 54 digital I/O ports, 16 analog inputs, 4 UARTs, and a 256KB FLASH memory, providing compatibility with Arduino MEGA2560. Ideal for long-term use and versatile projects, it can be powered via USB, adapter, or battery. This microcontroller is part of DFRobot's educational products, offering reliability and expanded creative space.
