DFRduino Mega2560 (Arduino Mega 2560 R3 Compatible) _MAKE_AUDIO Digital IO: 8The newly updated DFRduino Mega2560 enhances its VIN power supply circuit by replacing the traditional LDO with a DC DC circuit, significantly improving safety and reliability. This change not only addresses overheating issues but also broadens the input voltage range, allowing the board to operate even with just a 3. 7V lithium battery. This microcontroller, based on the ATmega2560, provides full compatibility with the Arduino MEGA2560 platform. It
