Hello,
I'm currently trying to connect a servo to test PWM output on AUX1 and nothing seems to work to get any real output to the servo.  I have supplied it with 5v power and currently have RC_MAP_AUX1 set to Channel 5.   And I have the servo signal wire connected to pin 5 on the PWM breakout board from plug J1007.  I assume I'm doing something wrong and hopefully someone can point it out to me, thank you!!![20211108_180042smol.jpg](https://forum.modalai.com/assets/uploads/files/1636413044687-20211108_180042smol.jpg) ![20211108_180051smol.jpg](https://forum.modalai.com/assets/uploads/files/1636413054536-20211108_180051smol.jpg) ![0ea6c981245ad99b7a30a57ec566b17e.png](https://forum.modalai.com/assets/uploads/files/1636413230508-0ea6c981245ad99b7a30a57ec566b17e.png) ![421f2b9685ac29b7550a8327196f3cce.png](https://forum.modalai.com/assets/uploads/files/1636413233132-421f2b9685ac29b7550a8327196f3cce.png)

Hi @Cole-Mathieu ,

We have a little bit of documentation here with respect to AUX outputs.  The FlightCore form factor only has the 8 PWM outputs, so it's a little limited, but we've used it to control a two channel gimbal:
