Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x Development Board 1. Embed Mega 2560 CH340G/ATmega2560: compatible with Mega 2560 motherboard. Built based on Atmel ATmega2560 microcontroller and USB-UART interface chip CH340G. 2. Compact Circuit Board: With its compact size, this development board is perfect for soldering onto prototype boards, allowing you to create a compact and stable final product. Its functionality is similar to the for Arduino Mega 2560, making it a reliable choice for embedded systems with the original ATmega2560 chip running at 16 MHz. 3. Stable Data Exchange: This board utilizes the CH340G chip as a UART-USB converter, ensuring stable data exchange when operating at a frequency of 12 MHz. To use it, you'll need to install the driver software on your computer. 4. Convenient Connectivity: The Mega PRO (Embedded) 2560 CH340G/ATmega2560 can be easily connected to your computer via a microUSB cable (compatible with most Android smartphones). This allows for hassle-free communication and programming.
