M5Stack Atom PSRAM/Lite - LCD Display Driver Kits

M5Stack Atom PSRAM/Lite - LCD Display Driver Kits are an all-in-one display driver kit and use FPGA to simulate traditional SPI TFT-LCD data output. These kits support images at a maximum resolution of 1280 x 720 pixels and provide an advanced signal with great precision colors. The LCD display driver kits feature an integrated 2.4G Wi-Fi® and dual-mode Bluetooth® with 8M Flash + 2M PSRAM memory combination, and RGB TO HDMI convert chip. This kit features multiple output modes that offer an optimized frame rate range from 12FPS to 16FPS with a maximum of 720P (1280x720) image output.  The Atom PSRAM/Lite - LCD display driver kits feature a built-in LT8618SX RGB to HDMI chip and ATOM PSRAM main controller. Typical applications include display input signal source and HD data board.
