2.1
Mounting
The four mounting holes are compatible with M3 screws. Use M3 3.5mm spacers. An
example of applicable SMD spacer is THF-1.6-3.5-M3 from MAC8.
All mounting holes are grounded, and should preferably be connected to ground on the
host PCB. Note however that the mounting holes should not be relied on as only ground
return connection: a proper ground should be supplied to the GND pins of the I/O
connector(s) as well.

Environmental
Operational: -40 to +85 °C
Storage:
-55 to +85 °C

Power and Power Consumption
The OEM module is powered through pin#1 and pin#2 of the 30-pin connector. Power
supply voltage must be 3.3V +/-5%.
The power consumption depends on the set of GNSS signals enabled with the
setSignalTracking
command.
The following table shows the typical power consumption of the OEM module (not
including the IMU) in dual-antenna mode for selected sets of signals:
Signals enabled with
setSignalTracking
Power
consumption
GPS L1+L2
1000 mW
GPS L1+L2, GLO L1+L2
1050 mW
All GNSS signals from all GNSS constellations 1115 mW
Enabling wideband interference mitigation with the
setWBIMitigation
command adds 80
mW.
Consumption in standby mode:
10 mW
In-rush current:
1.3 A during less than 100 µs
Maximum peak current during operation: 0.5 A
