ATOM Display Lite is a cost-effective display driver that uses an FPGA to emulate traditional SPI TFT-LCD data output, supporting up to 720P (1280x720) image output. It achieves broad compatibility for display output through a dedicated RGB-to-high-definition multimedia signal chip. Built with an embedded ESP32 controller, it integrates 2.4G Wi-Fi and a memory combination of 4M Flash + 520KB SRAM. ATOM Display Lite can replace traditional PC-controlled display panel solutions, offering a more cost-effective alternative.
