KEHIPI e-Paper ESP32 Driver Board development board

Universal e-Paper Driver Board

The KEHIPI e-Paper ESP32 Driver Board is a universal development board designed to drive compatible SPI e-Paper raw panels. It features an onboard ESP32 system-on-chip providing both WiFi and Bluetooth connectivity. This hardware targets makers and developers building wireless display applications or IoT edge devices requiring low-power visual output.

Sustained wireless operation

Under continuous use the board maintains a wireless link to refresh display content from a remote webpage or a smartphone application. The onboard ESP32 handles image processing tasks such as Floyd-Steinberg dithering for supported formats including BMP JPEG GIF and PNG. Developers can integrate the open-source driver and supplied resources into long-running wireless projects without relying on short-burst transfers.

SPI panel compatibility limits

The product only works with specific e-Paper raw panels that lack an integrated driver board; it is not compatible with every SPI e-Paper model on the market. Buyers who need a different panel size or a panel that already includes its own driver cannot use this board. Verification of the exact compatible model list is required before purchase to ensure the hardware matches the intended display.
