Checked November 1, 2026. "Not listed" means the maker and official docs don't state it.
Known issues and cautions
From the maker's documentation and the official Meshtastic docs.
- Meshtastic docs: 18650 holder only fits unprotected flat-top cells; button-top/protected cells are typically too long.
- Meshtastic docs: do not proceed with flashing unless an antenna is connected.
- Meshtastic docs: micro-SD reader not implemented in Meshtastic.
Where sources disagree
- Meshtastic page says SoftRF is preinstalled (Meshtastic must be flashed); the lilygo.cc 'T-Beam SUPREME Meshtastic' listing says Meshtastic firmware.
