FPV gear
The FPV gear is designed to be installed on the front section of the frame to achieve as much separation
between the R/C- and FPV-radio environment as possible. Keep in mind that the former is listening while the
latter is broadcasting. The quieter the receiving conditions are, the better range and reliability will be.
At the heart of this system sits the (optional) TBS CORE which provides a rudimentary OSD and clean power
distribution to the camera and video transmitter, regardless of input voltage. The frame already includes a
current sensor (50A) that works together with the TBS CORE to show current consumption during flight.
Power supply
● To eliminate noise from causing problems on the FPV-side of the system, use a properly filtered power
supply. Any type will work but the TBS CORE is made to provide selectable 5V and/or 12V to the video
transmitter and camera regardless of input voltage (2S to 10S). It can supply video transmitters with up
to 1W (with minor airflow at 1W) of emitted power (EIRP) and a standard FPV camera.
● If you are planning to fly with UHF, we highly recommend the Tin Shield to isolate the CORE nicely from
the rest of the electronics on board.
● Configure the CORE according to the required voltage for the FPV gear; pads marked VTX and CAM can
be configured to either 12V (0.65A max.) or 5V (2A max.). Solder a bridge between the middle pad to
either side for 12V or 5V. Do not solder all three pads.
Pilot camera
● Use the supplied camera plate to mount the pilot camera. The mounting pattern is designed to be
compatible with most standard 32x32 mm board cameras. You might need to break-away excessive
board support. Either use two small zip-ties, rubber bands or four M2x15mm screws and nuts (not
supplied) to mount the camera (use threadlock.)
● Plug in the cable connector for the camera and insert the tabs on the top and bottom of the camera
frame in the corresponding routed gaps on the frame. For a secure mount, you can add solder to the
three exposed solder spots (v1.3 boards or later), or leave it for easy hot swapping in the field.
● Decide whether you can use the supplied wires and connector socket on the top frame or connect the
camera and video transmitter via the round solder pads. The supplied picoblade Molex cable “5V VTx”
are designed to work with the TBS GREENHORN, TBS ROOKIE, Lawmate video transmitters, and the
supplied “12V CAM” cable with the TBS59/TBS69 cameras respectively. You can of course modify and
solder the wires to suit your specific need.
