Maker listing checked Sep 17, 2026. Detailed documentation reviewed Sep 17, 2026. Not hands-on tested.

Price is a dated listing; confirm with the maker.

Specifications were read from LILYGO’s product page on 2026-09-17; price US$52.37 and availability are as shown that day.

LILYGO sells several boards in plain and Meshtastic-preloaded versions and in regional band variants; this entry covers the model, not one variant.

Capability corrected 2026-09-19: this entry carried a 5 GHz Wi-Fi flag that its own recorded specifications do not support. Removed rather than guessed; if the maker documents 5 GHz, add it back with the source.
