Hello, I just purchased a VOXL 2 flight deck with 5G modem support.($3k) I was wondering if the VOXL 2 comes with PWM control? Or do I need an extension board?

No, the QRB5165 does not have PWM output. There is an add-on [VOXL 2 IO](link url) or you can communicate with our [4-in-1 ESC](https://docs.modalai.com/modal-escs/) directly using UART
