Micro-USB port: PC connection for configuration and firmware
upgrades.
CAN-Bus port: MC uses CAN-Bus to
power and communicate with other
WKM modules.
1. You can use T and R ports for gimbal control only if you choose D-Bus and Octo-rotor in assistant software.
2. If you open the gimbal control in assistant software during the configuration, please note that there is output from F1 and
F2 ports. Now you should not connect these ports to ESCs which is wired with propellers equipped motors.
Power Management Unit
 PW Port
This port provides power to whole WKM system (MC, IMU, GPS, LED) which does not need to get power from any 3-pin servo port.
The output voltage is 12.6V If input voltage from battery is higher than 13V; the output voltage will follow the change of input voltage
(0.4V lower than it) If input voltage from battery is lower than 13V. Its maximum output current is 2A.
WKM can still get power from 3-pin servo ports if the PW port does not function well.
 V-SEN Port
This port has two functions: 1) It collects the power input of the PMU for MC to monitor the battery voltage. The white wire from this
port is the signal wire, and its maximum output voltage is 3.3V, so it will not damage your receiver if you connect this port to it. 2) It
provides a 3A@5V power on red wire for the receiver and other electronic device through X1 port on MC.
1. Since the working current of some gimbal servos are large, this port may not drive three axial gimbal, please use extra
high-power UBEC.
2. Our BEC in PMU is powerful enough to drive receiver and most of the other electronic devices. However if you want to
use other BEC, you’d better use a 3-pin servo cable without red wire to connect V-SEN and X1 on MC.
