I’d prefer to buy off you than amazon.
Some of the products in the BOM I see you sell. Like the xiao, meshtastic hat, and foam tape. Do you sell the battery, the battery holder, and the aerial?
The aerial and cable should be a good match for the Wio-SX1262 on AU915. The only part I’d double-check before printing is the holder: ours measures 74.5 × 21.5 × 17.7 mm, and the Amazon one used by the designer may be slightly different.
No, I mean the 18650 battery enclosure. The internal dimensions can be different to accommodate certain 18650 vs others (with or with protection circuits, for instance).
