No frame at all: the firmware is open, the panel is a catalog part, and the protocol works the same whether we soldered the board or you did.

​
The parts

  • An ESP32-S3 board. The firmware targets the Seeed reTerminal E1004 (a complete enclosure with the panel already attached) and the XIAO ESP32-S3 Plus on the EE02 driver board.
  • A 13.3 inch E Ink Spectra 6 panel, 1200 by 1600. This is the only panel the panel format targets; smaller Spectra 6 sizes need their own driver work.
  • A battery if you want it on a wall, USB power if you do not.

​
The path

  1. Clone flightportrait/frame, build with ESP-IDF: idf.py set-target esp32s3 && idf.py build.
  2. Before involving any network, prove the glass: arduino-sd-demo/ blits a rendered panel image straight from microSD, so a bad panel cable never masquerades as a server problem.
  3. Flash the firmware, then pair it like any frame. The pairing flow accepts your own server URL, so a self-built frame usually goes straight to a self-run server: Bring your own server.
  4. first-flash/ in the repo is the box-opening sequence we use on our own hardware, with test images and a one-page failure tree. It works the same on yours.

​
What to show on it

Anything that renders to 960,000 bytes in six inks. The reference server ships with the tooling to serve a static image; from there it is your renderer against the same panel format we use, specified byte by byte in PROTOCOL.md.
