4.2 The Power Connector
4.2.1 Purpose of Power Connector
For both fixed wing and multirotor types, the Power connector lets you provide power to your video
equipment, and additionally lets you monitor your flight battery, and provide 5V power to the MicroVector.
The Power connector typically connects to a PDB, or the Eagle Tree PSU.
4.2.2 Power Connector Pinout
The power connections are described below (note
voltage limits in red):
Volt Mon: For connection to your flight pack, if you
want to monitor its voltage. 6s/26V max!
Current: For connection to an analog current sensor.
The system is precalibrated for the Eagle Tree PSU,
but can be recalibrated via the software for most
other sensors. See section 8.5.1 - ‘Electrical
Calibration’ later in the manual. 3.3V max!
Ground (2x): These connect to the ground of your PDB, BEC, or negative battery lead. Connect both wires to
the same location.
Cam Pwr In: This connects to the correct voltage for your video camera (typically 5V or 12V) 26V, 1A max!
VTx Pwr In: This connects to the correct voltage for your video transmitter (typically 5V or 12V) 26V, 1A max!
5V Power: Typically this is connected to a 4.2V to 6V power source when used with multirotors, to power the
MicroVector. Note that all the “5V Power” connections are connected together inside the MicroVector. Don’t
connect a power source to more than one of these connections! 4.2V Min, 6V Max!
4.2.3 Providing power to your Video Transmitter and Camera
Powering your video equipment is typically very easy with the MicroVector.
Here are typical wiring strategies, depending on the number of batteries desired, transmitter and camera
voltages, etc.
Video Setup
Wiring Method
12V Camera
Connect the Cam Pwr In wire to a 12V source
5V Camera
Connect the Cam Pwr In wire to a 5V source
12V Video Transmitter
Connect the VTx Pwr In wire to a 12V source
5V Video Transmitter
Connect the VTx Pwr In wire to a 5V source
High Voltage Video
Transmitter
Some transmitters contain built-in regulators, and can handle greater than 12V.
In this case, if recommended by the transmitter manufacturer, you can connect
the VTx Pwr In wire directly to your pack, assuming your pack voltage is
supported by your transmitter.
Make sure that you do not make a mistake in the wiring that causes too high voltage to be used with a
lower voltage camera or transmitter! This will likely destroy the camera or transmitter.
