DC_GH3

Dingchang's DC_GH3_V01 is a dedicated motherboard development board for game consoles (such as amusement equipment, coin - pusher machines, and children's game machines). It uses the Allwinner H3 main controller with a Cortex - A7 architecture. It supports H.265 4K 30FPS hardware decoding and integrates the SMARTCOLOR vivid color display engine, meeting the functional requirements for human - machine interaction, gaming, and video playback.

The board's shape and interface functions have been optimized. It measures only 78.5*71.5*18mm, retaining only display, audio, serial port, and USB functions. It offers high cost - effectiveness with a significant price advantage and enables rapid mass production. Dingchang provides API code references for system calls and offers the Allwinner H3 game console Android firmware for download.
