BETAFPV designed new BEC board for GoPro HERO8. This BEC board only weighs about 1.5g, which makes your naked GoPro super neat and light. This BEC Board has integrated 5V@2A BEC, stock GoPro buttons, and LED pluggable connectors and remote recording!
The two buttons on the BEC board have the same functions as the GoPro spare buttons. Three actions we will use frequently.
Under normal operation, plug the GH1.25 connector into the GoPro Lite camera firstly, then connect with the battery. The LED will flash once, then you should press the Power/Mode button once in a second to power on. The LED on the BEC board has the same status as the stock LED on the GoPro mainboard.
Indication | Button Operation | LED Status |
Power On | Press the Power/Mode button once | Flash 3 times and light off |
Power Off | Press the Power/Mode button for 5 seconds | Flash 7 times and light off |
Start Record | Press the record button once | Continuously slow flash |
Stop Record | Press the record button once | Flash 3 times and light off |
Mode Switch | Press the Power/Mode button once | Check the mode on LCD Display |
The pilot could use the switch on the radio transmitter to start/stop the record. Some more configuration needed.
Usually you would map the LED pin to allow for record start/stop functionality using betaflight resource mapping
We use the Pinio function in Betaflight to control the record. First, setup the Pinio function of the LED pin in the FC board.
resource LED_STRIP 1 NONE
resource PINIO 1 A08
set pinio_box = 40,255,255,255
save
Next, map one of the switch channels in your radio transmitter to this Pinio (aka USER1). As shown below, we map the AUX4 channel in the radio transmitter to USER1 Pinio. The cursor in the orange zone means button released and the white zone means pressed. So keep the cursor in the orange zone in default.
Third, check if the Pinio function works. Change the switch and make the cursor move from the orange zone to the white zone, and finally back to the orange zone. Now you could check the LED status to know if the record starts. Use the same process to stop recording.
