Hello everyone. I have acquired a Sentinel to which I want to connect a deploy servo. I have seen that I need the IO Board, but I see that the signal it handles is 3.3V, and most servos operate at 5V. Is there any problem in this regard? Should I power the servo with 5V independently and only give the PWM signal to the IO Board servo? Do you know of any servo compatible with this function? Thank you very much in advance.

@ valvarez said in PWM Servo IO Board : @ valvarez that is correct you should power your servo from another power source capable if giving off 5V - if the servo has an operational range though of 3.3-5 then you can power it from the IO board. Thanks Zach

Hello.
I have tried this command following what you mentioned and it doesn't work.
Is there anything special I have to try?
Is it possible to connect the IO Board to the UART /dev/ttyHS2 taking this into account in the firmware update bash script?

@valvarez , the usage for the test tool is as follows:
```
voxl2:/$ qrb5165io-uart-test -h
Description: runs hardware loopback test on specified bus

Usage: qrb5165io-uart-test

    -d <device ID> (eg 3 for /dev/ttyHS3)
```
So you should run your test as:
```
voxl2:/$ qrb5165io-uart-test -d 2
[INFO]: success!
```
