⚡ Seeed Studio launches OpenDisplay e-Paper kits

Seeed Studio has introduced two Bluetooth LE e-paper kits based on the Nordic nRF52840 microcontroller. These devices come preloaded with the OpenDisplay open-source firmware, which supports integration with Home Assistant. The launch targets users seeking low-power display solutions for smart home applications.

The OpenDisplay 4.26″ Mono Kit features a 4.26-inch monochrome e-paper display with a resolution of 800×480 pixels. It supports black and white operation by default, with an optional 4-gray mode. Partial refresh is available in black-and-white mode only, utilizing a Seeed XIAO EN05 driver board for control.

The OpenDisplay 7.3″ Color Kit is equipped with a 7.3-inch Spectra 6 color e-paper panel. It shares the same 800×480 resolution as its monochrome counterpart. Both kits are powered by a 2,000 mAh battery and include physical buttons for user control and system reset.

Under the hood, both models rely on an Arm Cortex-M4F microcontroller running at up to 64 MHz. The system includes 256 KB of SRAM and 1 MB of flash storage. Connectivity options encompass Bluetooth LE 5.0, NFC, and 802.15.4 protocols, ensuring versatile wireless communication capabilities.
