Radio equipment needs certification where you live (FCC, CE, UKCA, ISED, Anatel). Some devices are uncertified or restricted in Brazil. Buyers are responsible for their local law.

Bring along
Band-matched antenna, suitable battery and revision-matched firmware.
Keep in mind
GNSS module and radio band vary; the battery is a separate item.

What’s published

Schematics published

LILYGO publishes full schematic PDFs (V3.0/V3.1 + core module) for T-Beam Supreme; no editable KiCad/Altium PCB source.

Research notes

All three schematic PDFs verified live in Xinyuan-LilyGO/LilyGo-LoRa-Series (master branch), matching the batch's known_links. LR1121 has its own Semtech product page (verified reachable) for the LR1121-radio SKU.

What still needs checking
  • The generic wiki names PCF85063ATL in its overview, but the board reference and V3.1 schematic identify PCF8563. The profile follows the schematic for V3.1.
  • Frequency labels differ between the store and generic technical tables; 144–148 MHz is a separately documented variant. Match the exact radio module, antenna, region and firmware rather than assuming every board covers every listed band.
  • The board reference’s LR1121 data-rate rows have swapped labels and include a low-power-setting caveat. Those rates are not repeated here; check current maker guidance for that variant.
  • Battery inclusion, enclosure, antenna and complete package contents must be confirmed on the selected order.
