Description

The Atomic Display Base is a high-definition monitor driver base for Atom series controllers. It uses an FPGA to simulate traditional SPI TFT-LCD data output and supports up to 720P image output, allowing monitor-based interfaces without a traditional PC display control scheme.

The Atomic Display Base integrates a Gowin GW1NR FPGA and an LT8618SX RGB-to-high-definition multimedia signal conversion chip. It combines an SPI interface for FPGA data handling with an I2C interface for the LT8618SX, giving Atom hosts a compact path to display dashboards, control panels, and monitoring screens.

Notice: Use monitors that support adaptive resolution scaling. On monitors without adaptive resolution support, display anomalies may occur. Supported development platforms are Arduino and ESP32-IDF. UIFlow is not supported yet.

Other Content

Before deployment, confirm the target monitor supports adaptive resolution scaling and select an Atom host with enough memory and performance for the required interface. The Atomic Display Base is suited to compact display systems where replacing a PC-based panel controller reduces system cost and size.

FAQ

What monitor resolution is supported?

It supports image output up to 720P at 1280 x 720.

Can it be used with any monitor?

Use a monitor with adaptive resolution scaling. Monitors without that function may show display anomalies.

Which development platforms are supported?

Arduino and ESP32-IDF are supported development paths, while UIFlow is not supported yet.
