I have a minicube F3. Can I configure betaflight to output pwm on a pin to control a camera switcher(from switch on taranis)
Can the led pin be repurposed?
Other possibilities?

hi flightmode0 welcome to intoFPV!

What kind of camera switcher?

I only see 4 PWM outputs and I am guessing they're for the motors as usual. When looking at the board there is an RX2 and TX2... maybe UART2? Could you use that? I am not sure if that's where your receiver hooks up though, it appears that it may connect near the LEDs

This is the product I looked at for my answer. If yours is different then let us know.  https://www.banggood.com/de/Eachine-Mini...gL3JPD_BwE

It depends on what kind of switching you need. Off the top of my head I can think of two ways to do what you want.

Using PWM, but unfortunately you don't have an extra one. With pwm you can get a micro pwm switch.

The other way would be to use a relay. Connect to beeper and change beeper tone to constant. So when you flip the beeper switch it, it switch the relay. But it also mean you have to remove all other beeper tone.

I have never tried these ideas, so take it as working ideas.

Thank you. This sees like a nice community.

I'm rather new to RC electronic in general.

That looks promising. Only problem is you don't have an extra PWM output on your FC. You might be able to remap PWM 5 to the LED.

Is there anything hindering soldering directly to a MCU pin, even if has not been broken out on the board?

I think I need to do some reading on this.

This is what I get when I type in resource list in the CLI:

can you type "resource" and post that?

I have not done anything to this flight controller yet. This will be my first real practice build (X2 ELF).

I did some research. My original idea is likely not going to work. You will probably have to use servo control on a switch. You will have to remap the servo output to the LED pad or beeper pad. Unfortunately, I have never mess with servo control and probably at the end of my knowledge to help you. Here is some reading you can do, and hopefully someone here can help you.

Thanks for the support. I found some videos on servo tilt and channel forwarding. Will link if useful.

I think I figured it out. Make sure you save a copy of your original resource assignments before making these changes.

In CLI type

resource led_strip none
resource servo 1 A08
save

You need to add a switch to your TX mixer. We will use AUX1(channel 5) as an example.

Go to the servo tab in the configurator (you might have to toggle expert mode). On the servo 0 line, check the A1 box.

Now you can wire your pwm switcher to the LED pad. In theory, this should work.

Nice. I wil gave a go at it when I get back home tomorrow.

Keep us posted
