Description:

ATOM Display Lite is an all-in-one display driver kit that offers a compact and powerful solution for driving TFT-LCD displays. It utilizes an FPGA (Field-Programmable Gate Array) to simulate the traditional SPI TFT-LCD data output, providing a versatile display driving capability.

The kit supports images at a maximum resolution of 1280 x 720 pixels (720P), allowing for crisp and clear visuals on compatible displays. It features a built-in LT8618SX RGB to HDMI chip, which enables a wide range of HDMI signal output options. This integration simplifies the connectivity between the kit and other devices, enhancing compatibility and ease of use.

In addition to its display driving capabilities, ATOM Display Lite integrates 2.4G Wi-Fi functionality. This feature enables wireless connectivity, allowing for convenient communication and control of the display kit. The kit also includes 4M Flash memory and 520KB SRAM, providing ample storage for images, data, and program code.

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