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.
