  • Ready-to-manufacture Gerbers and drill files have not been verified.
  • A complete matching enclosure design has not been verified.
  • Firmware source and flashing instructions need review.

One ESP32-C5 scans and talks to the phone over BLE, so it scans Wi-Fi or Bluetooth one at a time. Storage is onboard flash; there is no SD card slot.

It went on sale on 9 October 2026 and sold out within about ten minutes; the store now takes restock sign-ups. It can join a Biscuit Pro or Ultra as a satellite node but cannot manage other nodes.

Still sold out when re-checked on 18 October 2026 (the store lists it as unavailable).
