From the project
Darknet SMAO: Meshtastic LoRa+BLE mesh node SAO for DEF CON 34
KiCad 9/10 project in kicad/v1.4/ (open v1.4.kicadpro`; custom libraries in kicad/lib/ resolve via relative paths). Fab outputs the production run was built from are in production/. Renders, populated-board photos, and the board outline drawing are in images/.
- 41.00 x 33.00 mm, 4-layer, SAO 2x3 header on the back. - RAK4630 module (nRF52840 + SX1262), two Johanson chip antennas with grounded-coplanar (GCPW) feeds: 0.294 mm trace / 0.2 mm gap on the outer layers, matched to the stackup below. - Power: SAO rail or USB-C, automatic mux (P-FET + diode), bulk cap for LoRa TX bursts.
