M5Stack Atom GW1NR - HDMI Display Base

The Atomic Display Base is an HDMI display driver unit that gives high-definition visuals with support for up to 720P (1280 x 720) output. Using FPGA technology, it emulates traditional SPI TFT-LCD data output, providing compatibility with a wide range of HDMI signal outputs through a dedicated RGB-to-HDMI chip. It pairs easily with ATOM series hosts, which in turn provides flexible memory and functionality configurations.

Note: The Atomic Display Base requires a display with adaptive resolution scaling. Some displays without adaptive resolution support may experience display issues.
