OpenDisplay 7.3" Color Kit

The OpenDisplay 7.3" Color Kit is a ready-to-use e-paper display, co-developed by Seeed Studio and OpenDisplay. It combines a 7.3-inch 800×480 Spectra 6 color e-paper panel, a Seeed XIAO EN04 driver board (nRF52840), a 2000 mAh rechargeable battery, and a 3D-printed case.

The kit ships fully assembled with OpenDisplay firmware and factory settings already installed. Power it on and start using it over Bluetooth Low Energy from your browser or Home Assistant. No Wi-Fi is required.

Unlike many ESP32-based e-paper displays that turn the radio off between updates, this kit keeps Bluetooth listening in a low-power mode. If the display is powered on and in range, you can send a new image at any time without a wake-up step.
