Mega2560 Pro ATMEGA2560-16U USB CH340G Development Board

Mega2560 Pro ATMEGA2560-16U USB CH340G Development Board

The Mega Pro Embed CH340G / ATmega2560 board is a microcontroller platform featuring the ATmega2560 chip and a USB-UART interface via the CH340G chip. This board is perfect for final projects on a soldering prototype board.

With the same capabilities as the Mega 2560, the Mega Pro Embed is a stable and reliable option, utilizing the original chip and high-quality 16 MHz quartz resonators. The CH340G chip facilitates seamless UART to USB conversion, ensuring stable data transfer at a frequency of 12 MHz (note: a driver must be installed on the computer).

Power the board or its pins through the Micro USB connector. The onboard voltage regulator (LDO) can accept input voltages from 6V to 9V (with a peak tolerance of 18V DC). While the regulator can handle up to 18V, it’s advisable to stay within the recommended voltage range to prevent excessive heat and potential damage to the device.

Frequently Asked Questions

Do I need to install any driver to use the USB interface?

Yes, the CH340G chip requires a driver on Windows to enable the USB-UART bridge. Download the latest CH340G driver from the manufacturer’s site, install it, then reconnect the board. macOS and Linux often recognize the CH340G natively.

What input voltage range does the onboard regulator support?

The onboard LDO regulator accepts 6 V to 9 V on VIN or the DC jack, with a maximum transient tolerance up to 18 V. For stable performance, keep the input between 7 V and 9 V.

How much current can I draw from the 5 V and 3.3 V rails?

Each rail (5 V and 3.3 V) can supply up to approximately 800 mA, depending on ambient temperature and input voltage. Ensure proper heat dissipation for higher loads.
