Wall Panel is a 4-inch wall-mounted touch display panel powered by Raspberry Pi Compute Module 4 (CM4). It features a 720x720 IPS multitouch display and can be used as a Home Assistant dashboard or any other embedded display application.
Display
We use this display, but touch variant. It is 4 lane MIPI with i2c touch controller.
- Display driver: ST7703
- Touch driver: FT6336U
Possible use cases
- Home Assistant Dashboard. Perfect for wall-mounted smart home control panels with full touch interaction and high-resolution display.
- Information Display. Show weather, calendar, news, or any other dynamic content in your home or office.
- Control Panel. Use as a centralized control interface for IoT devices, lighting, or home automation systems.
- Embedded Display. Build custom applications using the full power of Raspberry Pi OS or any Linux distribution on the CM4.
List of features

Questions
How big is the Wall panel PCB?
It measures 75 × 79 mm and has 8 copper layers, 1.6 mm thick.
What parts does the Wall panel use?
117 parts, built around the 74LVC1G07SE-7-MS, LM3630ATMX, AP22653W6 and DS3231MZ+. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Wall panel KiCad files?
From the dotstartech/wall-panel repository on GitHub, at the commit this page was made from: the board is pcb/wall-panel/wall_panel.kicad_pcb and its schematic pcb/add-on-nfc/add-on-nfc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wall panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask dotstartech before reusing the design.
