Why Join Powerus

The radios in Powerus controllers and aircraft run firmware that controls the transceiver, selects channels, manages frequency hopping, and carries command, telemetry, and video between them.

This role develops that radio firmware, from transceiver drivers through the link layer that decides how traffic is scheduled and how the link recovers from interference.
