This is a preliminary datasheet and is subject to change
The Tracker One is a ready-to-go Tracker SoM carrier board with optional weatherproof enclosure.
- Ready to go with IP67-rated enclosure.
- GNSS Antenna Onboard: convenient high-gain GNSS antenna for easy access to GNSS signals.
- Flexible Power Supply: easily add asset tracking to most devices. A wide 4.5-30V power supply copes with most power delivery systems. Also accepts 5V supply via USB-C. LiPo battery connector, charge LED, backup battery for GPS and battery-backed RTC. Supports up to 105V when connecting directly to the carrier board.
- High-precision Thermistor with accuracy to 1%.
- Extensible: IP67-rated M8 connector includes CAN Bus, UART, GPIO, and power for simple expansion.
- USB-C for flashing, debugging and power with higher charging rates than Micro-USB or for use without an internal battery.
- RGB LED for use as both a user-configurable device as well as Particle status information.
- Backup Battery for RTC and GNSS.

This connector attaches to the IP67 M8 connector, accessible from the outside of the enclosure. The connector on the Tracker One enclosure has male pins and a barrel threaded on the outside.
1MCU GPIO is limited to 3.3V maximum.
2CAN Bus specifications can be found in the Tracker SoM datasheet. CAN Bus termination is provided on the carrier board.
34.5 to 30 VDC when using the M8 connector. 4.5 - 105 VDC when connecting directly to the board.
45V, 500 mA maximum. Controlled by the CAN_PWR GPIO.

There are several options for powering the evaluation board:
The MCU USB connector (USB-C). If using a laptop with a 500 mA USB port, you should also use the LiPo battery. With a 2A tablet charger, you can power only by USB.
The VIN connector (5-30 VDC). This is useful with an external power supply.
The LiPo connector. This is typically used with a LiPo battery.
There are two USB connectors on the carrier board, however you most commonly will only use the MCU USB connector.
The MCU USB connector is connected to the nRF52 MCU and can be used for Serial debugging, flashing code, and setup by USB. It can also power the AssetTracker SoM. If using a laptop with a 500 mA USB port, you should also use the LiPo battery. With a 2A tablet charger, you can power only by USB.
The GNSS USB connector is connected to the u-blox NEO-M8U GNSS. It can be used for firmware upgrades or with the u-blox u-center application.
The RGB LED default behavior is to display cellular signal quality:
- Red blinking: Attempting to connect to the cellular network
- Red: poor cellular signal
- Yellow: average cellular signal
- Green: good cellular signal
It will fast blink when connecting to the cellular network, and slow blink when connecting to the Particle cloud. This behavior can be overridden by custom application firmware.
The CHRG LED indicates the charge status:
- Off: Not charging or no power
- On: Charging
- Blinking: Charge fault
- Flickering: No battery
The GNSS LED indicates the GNSS fix status:
- Blinking (1 Hz): Attempting to get a GNSS fix
- On: Has a GNSS fix.
