LoRa Typie-Walkie with E-Paper Screen

8/13/2022

 
The initial version of the typie-walkie project used WiFi as radio. However, WiFi does not match the low-power feature of the e-paper screen.

Which radio to feature low-power? LoRa came up as a good alternative for short messages over long distances.

The new version runs on the iLabs Challenger RP2040 LoRa board, which combines a RP2040 MCU with a RFM95W-SX1276 sub-1 GHz radio.

Discover the new version of the project.

IoT Typie-Walkie with E-Paper Screen

8/9/2022

 
Everyone knows the talkie-walkie, but sound requires a large bandwidth. Here is a variant with an e-paper touch-screen.

The capacitive touch turns the e-paper screen into a human-machine interface. The user type the message with the keyboard and then press Send. The message is sent and displayed on the remote screen.

Discover the full project.

HMI with EPD Extension Kit Gen 3-1 and EXT3-Touch

8/2/2022

 
The last revision of the EPD Extension Kit Gen 3-1 supports the EXT3-Touch, an expansion board for touch​. With this combination, Pervasive Displays​ brings a whole new dimension to e-paper displays. 

​Instead on being passive devices, e-paper displays are now active input devices, perfectly suited for ultra-low power human-machine interfaces (HMI).
