USB power source. The charging status is indicated by a red LED which is on during charging and
turned off when fully charged.
When less than 500 mA is available from the USB host, ensure sufficient extra supply via the DC power
jack. Note that due to the higher current consumption caused by the battery charging it is not
recommended to charge the battery via USB only.
☞
Supplying through the USB port requires the power source (USB host) to support the USB
enumeration process. If the power source is not capable of enumeration, you may use the provided
USB-to-DC adapter cable and connect it to the DC plug. There is no current limitation for the DC
supply.

4.1.1 Non-wireless operation
For use-case scenarios where non-wireless data link is needed the ODIN-W2 can be disabled. In order
to disable the ODIN-W2, connect the safeboot jumper which forces the ODIN-W2 into safeboot mode
during the device start-up. See Figure 6 to locate the safeboot pins.
On average, the ODIN-W2 consumes less current when started in the safeboot mode. In addition, the
safeboot mode ensures that no intentional radiation originates from the 2.4 GHz antenna connector.
4.2 GNSS RF input
The C099-F9P board should be used with the antenna supplied with the kit. If another active antenna
is used, be aware that the RF input has a bias output designed to supply 3.3 V DC with a 70 mA
maximum current load. A DC block is advisable if the board is connected to a signal distribution
scheme or GNSS simulator to prevent any potential shorting of the antenna bias.

When using the supplied antenna it is advisable to use the ground plane provided. Otherwise ensure
that there is an adequate ground plane, e.g. by mounting in the center of a metallic car roof.
