Product details
The GEPRC O4 Series Step-Down BEC is a 1g regulator that sits between the flight controller and a DJI O4 Air Unit or O4 Air Unit Pro, feeding the air unit a clean, regulated supply from a 3-6S pack. Use it on boards whose own VTX rail cannot power the air unit properly, or to switch the air unit on and off from your radio.
Key features
- 9V output by default; bridge the 5V pad on the underside for 5V
- Plug-in 6-pin IN and OUT connectors, clearly marked to prevent reversed wiring
- UART TX/RX and SBUS pass straight through the board
- EN pad for output switching: wire it to a spare FC pad, assign PINIO in Betaflight and toggle VTX power from a radio switch
- Extra G and 5V pads can also power an LED strip
Specifications
- Input: 3-6S (10.5-25.2V)
- Output: 9V default, 5V selectable
- Connector pinout: +, GND, TX, RX, GND, SBUS
- Size: 17 x 8.3mm
- Weight: 1g
- In the box: 1x BEC, 1x 6-pin cable (6 wires), 1x 6-pin cable (4 wires), heat-shrink
Never feed it more than 25.2V, so 7S and 8S packs are out, and remember it only steps voltage down: it will not raise a 2S supply to 9V. You can skip it if your flight controller already has a 9-12V BEC rated for the air unit's draw.
