Product description: Atomic Display Base - HDMI display driver - GW1NR-9C - expansion module for M5Atom - M5Stack A115
Atomic Display Base is an HDMI controller that uses an FPGA (Gowin GW1NR-9C) to simulate the classic SPI output for TFT LCD displays . With the built-in LT8618SX RGB-HDMI converter, it supports image resolutions up to 1280 x 720 px (720p) at 60 Hz and 24-bit color depth. The module communicates via SPI and I2C interfaces and offers various output modes with frame rate optimization (from 12 fps to 16 fps). This is a great solution for projects requiring economical and compact display control. It is supported by the Arduino environment and ESP32-IDF .

Atomic Display Base - HDMI display driver - GW1NR-9C - expansion module for M5Atom - M5Stack A115.
Botland is an official distributor of the M5Stack module family in Poland. We have extended this system of stackable functional devices with accessories from our range and numerous blog guides. All M5Stack products presented here are original.
The output signal is converted from RGB using the Gowin GW1NR-9C FPGA.
Key Features of the Atomic Display Base
- Atom Series Compatibility : Works with Atom Lite, Atom Matrix, Atom S3 and S3 Lite modules
- HDMI 720p output : supports maximum resolution up to 1280 x 720 px
- 24-bit color depth : image conversion by the LT8618SX chip provides a rich palette of colors
- RGB to HDMI conversion : using the Gowin GW1NR-9C FPGA
- Dual-channel communication : SPI interface for FPGA and I2C for HDMI converter
- Compact size : small housing measuring 64 x 24 x 29 mm
- Lightweight and energy-saving design : weighs only 15.2 g with low power consumption
- Support for popular environments : programming in Arduino and ESP32-IDF
- Alternative to PC as controller : enables cheap and mobile display control without a computer
Compatibility and connection
The Atomic Display Base is designed to work with M5Stack's Atom series modules , such as the Atom Lite , Atom Matrix , Atom S3 , Atom S3R and Atom S3 Lite . Communication is via SPI and I2C buses - the appropriate pins should be assigned according to the documentation. Remember to adapt the source code to the actual pin layout . The module requires the use of a display that supports resolution scaling - otherwise the image may be displayed incorrectly.
The module supports Arduino and ESP32-IDF programming platforms.
Available communication interfaces are SPI (FPGA) and I2C (HDMI chip).
Practical applications
- Display Drivers for IoT and Automation Systems
- Intelligent information panels for home and office
- Multimedia presentations in education and at conferences
- Diagnostic dashboards for data monitoring
- Displays for remote viewing and control of systems
Attention!
Atomic Display Base requires a monitor that supports automatic resolution scaling . Screens that do not have this feature may experience issues with displaying the image.
