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 6-30V 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 90V 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.

1When disassembling the Tracker One, be careful when removing the lid. The NFC antenna and LiPo battery are mounted on the lid, and the NFC antenna cable is short. Carefully remove the NFC U.FL connector before fully removing the lid of the case. Reconnect to (9).
2The USB-C connector is normally connected to the nRF52840 MCU. It can be connected to the GNSS module by using the USB-C switch (17).
3The normal state is 1-4 OFF and 5-6 ON to connect the USB to the nRF52840. To connect the USB-C to the u-blox GNSS, turn 1-4 ON and 5-6 OFF. Disconnect the USB-C and the LiPo battery before changing the switch settings.
4The JTAG connector is not populated at the factory. The connector is a Samtec FTSH-105-01-F-DV-K 10 position (2x5), 1.27mm pitch.

The IP67 M8, 8-pin, male pins with threaded barrel connector is accessible from the outside of the enclosure.
View as looking into the M8 connector on the outside of the enclosure.
Note: Version 003 and earlier of this datasheet had a different pin numbering for M8 connector that didn't match the connector manufacturer's numbering. Only the numbering has changed; the function of the pin at a given location is unchanged and the change should not affect existing designs.
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.
36.0 to 30 VDC at 2A when using the M8 connector. 6.0 - 90 VDC at 2A when connecting directly to the board.
45V, 400 mA maximum. Controlled by the CAN_PWR GPIO.
Additional information on M8 cables and connectors can be found in the M8 Accessories Datasheet.
The connector on the carrier board itself is is a JST B8B-PH-SM4-TB(LF)(SN), 8-position, 2mm pitch, male pins, shrouded. The mating connector is the JST PHR-8. The female sockets are available plain, with leads, and in pre-manufactured ribbon cable formats.

Note: While the USER button exists inside the Tracker One, the Tracker One is a sealed unit and opening it will void the warranty and may affect certifications, thus it is not practical to use. It can be used with the Tracker Carrier Board.
There are several options for powering the carrier board:
The MCU USB connector (USB-C). If using a laptop with a USB-A to USB-C cable and a 500 mA USB port, you should also use the LiPo battery. With an true USB-C port and cable, or a 2A tablet charger, you can power only by USB.
The VIN connector (6 to 30 VDC at 2A on the M8 connector, or 6 to 90 VDC at 2A to the B8B-PH connector on the board). This is useful with an external power supply.
The LiPo connector. This is typically used with a LiPo battery.
There is a single USB C connector on the carrier board. On the Tracker One, this exits the enclosure and is IP67 rated.
A set of DIP switches on the carrier board allow this port to be connected to either the MCU (normal) or u-blox GNSS (for firmware updates). The normal state is 1-4 OFF and 5-6 ON to connect the USB to the nRF52840. To connect the USB-C to the u-blox GNSS, turn 1-4 ON and 5-6 OFF. Disconnect the USB-C and the LiPo battery before changing the switch settings.
The RGB LED default behavior is:
- Red breathing: Attempting to connect to the cellular network
- Yellow breathing: Connecting to the cloud, weaker cellular signal
- Green breathing: Connecting to the cloud, good cellular signal
- Yellow solid: Connected to the cloud, weaker cellular signal
- Green solid: Connected to the cloud, good cellular signal
Alternatively the LED can be configured to the typical Particle color scheme (blinking green, blinking cyan, breathing cyan) via device or cloud configuration. Custom device firmware can provide other color schemes if desired.
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:
- Off: GNSS is powered off.
- Blinking (1 Hz): Attempting to get a GNSS fix
- On: Has a GNSS fix.
|GNSS||Carrier Board (faces top of case)|
As the GNSS antenna faces the top of the case, you also want the top of the case facing the sky to the greatest extent possible. You will likely be be unable to get a GNSS lock with the top facing down.
Will be provided at a later date.
The Tracker Carrier Board contains a 100K NTC thermistor, connected to A0. It is a Panasonic ERT-J1VR104FM connected high-side.
It can be read using the getTemperature() API.

Note: The Tracker Carrier Board has a smaller bottom tab to provide space for the M8 connector.
The Tracker SoM contains highly sensitive electronic circuitry and is an Electrostatic Sensitive Device (ESD). Handling an module without proper ESD protection may destroy or damage it permanently. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates the module. ESD precautions should be implemented on the application board where the B series is mounted. Failure to observe these precautions can result in severe damage to the module!
This device must be treated as Waste Electrical & Electronic Equipment (WEEE) when disposed of.
Any WEEE marked waste products must not be mixed with general household waste, but kept separate for the treatment, recovery and recycling of the materials used.
