Quick Start
Five steps from a fresh CollarID Mk II to a synced, deployable device. About 30 minutes total.
Charge to full
Open the cover (six screws around the perimeter) and connect a USB-C cable to the port on the top edge of the front PCBA. The cover must come off — there is no pass-through.
- Charge LED red = charging in progress
- Charge LED green = battery full, ready to deploy
Format the SD card as exFAT
Use a freshly formatted exFAT card. We recommend industrial-grade Kioxia cards — they handle power loss, sustained writes, and field temperatures better than consumer cards.
- macOS: Disk Utility → Erase → Format: ExFAT
- Windows: Right-click the drive → Format → File system: exFAT
Power on, outdoors, with a clear sky
Insert the formatted SD card and slide the side power switch to ON (silkscreen-labelled). Bring the device outside before powering on so it can acquire its first GPS fix.
You should see this LED sequence on the paw print:
- Boot animation (green pulse → soft white-cyan glow → off)
- Steady green — SD card is being scanned
- LED off briefly
- Flashing blue — searching for GPS fix (up to 10 min)
Configure a schedule via BLE
A freshly formatted SD card causes the device to enter BLE mode automatically (steady blue LED) once boot finishes. Connect from one of:
- Web: CollarID.org → Configure (Chrome or Firefox only)
- iOS: the CollarID app on the Apple App Store
- Android: the CollarID app on Google Play
Edit your schedules (up to 5 windows), check the power-budget estimate, then disconnect. The schedule commits when the steady blue LED turns off ~10 seconds later.
Full schedule procedure →Verify the GPS fix and close it up
Confirm the flashing-blue LED has turned off on its own — this means the device acquired a GPS fix and synced its clock. If the LED times out after 10 minutes, the device will run unsynced; bring it outside again and re-trigger BLE with a magnet to restart.
Replace the cover, hand-tighten the six screws in a star pattern (do not use an electric drill), and the device is ready to deploy. For long deployments, apply Loctite 242 or 243 (medium-strength blue threadlocker) to the first 2–3 threads of each screw before closing.
