Hardware
- U1 — Seeed Studio XIAO nRF52840 (MCU + BLE, handles charging and USB)
- U2 — Wio-SX1262 LoRa module
- J1 — 2-pin JST 1.25mm connector for a single-cell LiPo battery
- SW2 — slide switch, gates power to the LoRa radio only (see below)
- J5 / J6 — solder pads for a hand-wired bodge to the XIAO's battery pads (see below)

Questions
How big is the Meshnode PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Meshnode use?
8 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Meshnode KiCad files?
From the Aiden-Jun/meshnode repository on GitHub, at the commit this page was made from: the board is meshnode.kicad_pcb and its schematic meshnode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Meshnode design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aiden-Jun before reusing the design.
