Issue dossier

Two community sources say the LoRa radio's interrupt and busy lines are not routed to the ESP32-C6. Lichen OS's README says the schematic draws an Ra-01 (SX1276) but an RA-01SH (SX1262) is fitted, and that without bodge wires on DIO1 and BUSY the radio answers over SPI while MeshCore's radio init fails.

A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.

LoRa pin routing · community firmware README plus wiki project page · bodge documented

Mesh firmware such as MeshCore or Meshtastic needs owner soldering before the radio works. The catalogue does not claim every badge has the same module or routing.

community firmware

Lichen OS

GPL-3.0 replacement operating system by Lucas van Schouwen, started October 31, 2026 as a fork of BadgeVMS: one ESP-IDF 6.1 application on the ESP32-P4 with a standalone MeshCore messenger, a clock, and settings, while the ESP32-C6 runs ESP-Hosted Wi-Fi and BLE and the SX1262 LoRa service. Source only, with no tag or release on November 5, 2026. Not a Team:Badge release.

Meshtastic on the WHY2025 badge

WHY2025 wiki project page for an attendee's Meshtastic port. It says Meshtastic needs the CAD and busy pins soldered between the LoRa radio and the ESP32, and that the screen and keyboard backlight PWM is wired to the C6.

Lichen OS README

Secondary community source. It says the schematic draws an Ra-01 (SX1276) while an Ai-Thinker RA-01SH (SX1262) is fitted with its DIO1 and BUSY pads unrouted, so MeshCore needs two bodge wires to C6 GPIO5 and GPIO11, and that the stock antenna is poorly matched at 868 MHz (SWR about 1.7 after tuning). It describes the author's badge and does not give a badge count.
