Input
Power supply input. The power supply must be able to
meet the requirements of current consumption. Care
must be taken so that the operating voltage applied to
the terminal stays within the voltage range. Applying a
voltage outside of the voltage range can damage the
module. For security reason, it is recommended to
integrate externally a 2A fuse link between power
source and DISCO-B4-GLONASS.

Input
General purpose input. Either connect it to the vehicle
ignition and use it for journey START and STOP reports
or connect it to the operating vIN and with the
help of an external switch you wakeup the DISCO-B4-
GLONASS device from IGN-Sleep mode
(awaking from
this mode requires a HIGH signal)
