Using SpeedyBee F405 AIO for fixed wing glider

[mu1q]

For a fixed wing glider I need 4 servo controls and 1 motor control. Is that possible with this controller?

If I set the timer outputs like in the picture below I can have all 5 outputs

However:

1. Does the motor control go through the internal bluejay ESC in this configuration.
2. For timer 5, do I connect both servos to the T5 pad on the controller? or one to T5 and the other to R5?
3. I cannot find the (timer 2) T2 pad on the controller, is it an internal pad that I cannot access?
4. T4 is available on the controller, is there a way I can use it?

No. Since it is an AIO is includes escs hard wired to the first 4 outputs, so there is no way to control servos with those outputs.

Thanks for the quick response!

The first 4 outputs are T0-3?

In the manual T3 can be used for analog VTX, which I am not using. The same for T5 with GPS and T6 with certain types of receivers. Can these outputs not be configured to handle servos?

T4 is not used for anything, as far as I can tell. Can it be used for servo output?

The first 4 outputs are T0-3?

No. As shown in the screenshot, they are S1 - S4. Which on your board are internally connected to the ESC. So they control the four motor outputs from the ESC.

T1 is the transmit side of of UART1. T2 is the transmit side of UART2. UARTs don't control servos.

That board has four of its five PWM outputs permanently connected to ESCs. It is not an appropriate FC for your project.

ok, thank you! Where can I find a list of appropriate FC's?

You'll want to avoid "AIO" boards. AIO typically means * it has four ESCs built into the board, which isn't what you want. Most boards that are not called "AIO" could be used.

Boards that have "wing" in the name will often be easiest because that means they have a power rail set up for servos, where you can just plug servos in without needing to figure out how to power them.

• The meaning of "AIO" changes over time, and means different things to different people. But in 2024-2025, it normally means at least the ESCs are embedded.

Great, thank you!
