Power supply for router is required b9 V to +36 V DC supply. Protection against
reversed polarity without signaling is built into the router.
The power consumption during receiving is 1.6 W. The power consumption when using
WiFi is 1.9 W. The peak power consupmtion during data sending is 2.5 W. However, values of
consumption can be increased, if some expansion port is eqquipped. For correct operation it
is necessary that the power source is able to supply a peak current of 0.5 A.
Circuit example:

The positive pole VCC is marked by a red socket on the power.
