The TRMNL 7.5" DIY Kit pairs a 7.5" 800×480 black/white e-ink panel with a Seeed XIAO ESP32-S3 on the XIAO ePaper driver board. Because the XIAO S3 has 8 MB of PSRAM, this kit runs the full on-device renderer - unlike the TRMNL OG, which is a thin client.
Pick the TRMNL 7.5" DIY Kit hardware preset when you add the frame and the panel, GPIO map, flash profile and the two buttons are set up for you.
Setup
- In the FrameOS backend, create a frame with Flash embedded device.
- Choose ESP32-S3, select the TRMNL 7.5" DIY Kit preset, and enter your WiFi details.
- Build the firmware and flash it over USB from the browser.
- Install scenes as usual - they sync over WiFi, and the device updates itself over the air.
Flashing FrameOS replaces the TRMNL firmware on the board. It does not touch, and does not need, a TRMNL account or their servers - the frame talks to your own backend.
Status
🟡 Should work, not yet confirmed on real hardware. The 7.5" V2 panel driver is confirmed on other ESP32-S3 boards. Tell us on GitHub or Discord if you try it.
