Firmware: 2026-04-21
Device : LilyGo T-Beam Supreme V3.0 SX1262 (https://wiki.lilygo.cc/products/t-beam-series/t-beam-supreme/)

The OLED works with recent Meshtastic firmware, but does not with the 2026-04-21 firemware. Some quick searching says the SH1106 OLED may be a change from other T-Beam firmware.

Otherwise, it looks like it boots properly when checking the logs via the web flasher. And it connects to my Wifi and I can use the admin UI.

Still configuring, and will flash a tracker next.

Please let me know what other information you may need. I do not currently have a PlatformIO environment set up, but will clone the repo and see what I can find.

Yes, forgot to mention that. I have two identical units, and will be flashing and setting up a tracker this weekend. I will let you know how that goes.

Oddly, I can't find a BSP for this device to 100% verify. It looks like the V3 is

SH1106
1.3" / 128x64
OLED_SDA: GPIO17
OLED_SCL: GPIO18

I can't confirm the actual I2C address from any official sources.

strange enough is that the Firmware for try tracker for your board forces to work with SH1106 board.

can you post a picture of your board and oled screen ?

I've just installed V4.0.0 on a T-BEAM-S3. I made sure to install the specific iGate firmware for that device. The iGate works fine, but the OLED shows only my call sign and SSID. No other info is displayed on the screen.

hi, V4.0.1 is ready to use with VSCODE. This next week I'll release it as web flasher with a few minor updates I need to add to it .
