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.

IGN
Blue
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 voltage
+IN and with the help of an external switch you
wakeup the DISCO-B4 device from IGN-Sleep
mode
(awaking from this mode requires a HIGH
signal)
