So using the SIN ↔ SERVO it’s equal to connecting VTX ↔ TX and VRX ↔ RX with the VESC’s COMM port?
Another question: can I get the batt voltage from another point in the circuit? So not directly from the BATT+ solder joint of the VESC?

That wouldn’t work without new software either, and it’d be considerably more expensive to do it that way, and it’d involve recurring costs instead of just an upfront cost, like adding a piezo element.

Uart needs +, -, tx and rx to communicate
Ppm/pwm needs +, - and signal wire to communicate.
Both should function identically with the controller, only difference is with pwm you have to calibrate first (inside vesc tool/metr app), while with uart it’s plug&play like a usb port on a computer.
You can get the voltage reading from any point in the circuit you can find the full, identical battery voltage. You can even stick it directly on the pack, or take the bottom cap off a xt connector and solder it there
Great! Thank you so much for the explanations!

I’m telling you from now that this kind of feature will not be on the priority list for vedder anytime soon. It might not ever make it into the main branch if there isn’t already a huge demand for it

Man…this thread went nowhere. I was hoping for my board to make some robot noises like my light sabers do. Maybe i could steal a soundboard out of one.

Also because he might die using the current one…
