M5Stack Atom PSRAM – LCD Display Driver Kit

The M5Stack ATOM Display is an all-in-one display driver kit allowing you to use FPGA to simulate traditional SPI TFT-LCD Data output.

This kit supports images at a maximum resolution of 1280 x 720 pixels. It provides an advanced signal with great precision on colours. It has integrated 2.4G Wi-Fi & dual-mode Bluetooth, with 8M Flash + 2M PSRAM memory combination and an RGB TO HDMI conversion chip.

So small yet powerful, which can replace traditional display driving solutions!

Note: ATOM Display needs to be paired with monitors with adaptive resolution scaling.

Features

• All codes of FPGA and driver library are open-source
• Use FPGA (Gowin GW1NR-9C) to simulate traditional SPI TFT-LCD Data output
• Built-in LT8618SX RGB to HDMI chip (supports 24bit colour depth)
• SPI interface (FPGA) + I2C interface (LT8618SX)
• Maximum 720P (1280×720) image output
• Multiple output modes, optimized frame rate up to 12 ~ 16FPS
• Built-in ATOM PSRAM main controller (ESP32-PICO-V3-02, 8M Flash + 2M PSRAM)
• Programmable RGB LED x1, reset button x1, button x1, Grove expansion port x1
• Development platform: Arduino, ESP32-IDF, (UIFlow support coming soon)
