Most Avisaro devices are powered through the Mico-USB client port, however only for configuration. A
stable regular operation is not guaranteed. Use the regular power supply for normal operation.
A “Micro USB” cable is used. As those cable are widely avail
able, this cable is not part of scope of
delivery to avoid electronic waste.
