Summary

Wireless Paper is an E-Ink development kit with multiple wireless drive methods. Collaborate with the sample programs and development tools we provide, users can operate the display via Bluetooth, Wi-Fi and LoRa. This board is equipped with a default 2.13-inch black and white E-Ink display screen, continuous display for 180 days after power outage. It can be used to develop applications such as electronic tags ons.

Highlights

USB Type C

The power supply, firmware download, and debugging

interfaces adopt a more universal USB Type C interface,

making development work more convenient.

Acrylic protective plate

Transparent acrylic protection plate provide basic

protection for the development board.

E-Ink Display

The integrated E-Ink display can be used to show some

information such as system status and parameters,

making it convenient for users to directly use the entire

development board for their own product design.

Wireless Paper supports the following development methods:

Wireless Paper is compatible with the following open-source projects:

ESP32 Paxcounter
Disaster Radio
Meshtastic
Tiny GS
...

We also provide a standard ESP32 Arduino LoRaWAN library:
