Tried to use Yahboom Dofbot Expansion Board[BUG]

[potSm0ker]

I have the yahboom dofbot expansion board connected to my jetson nano. I am trying to use the pwm servo interface(8) on the board to drive a servo. However, I am only able to control servos connected to the bus servo interface(11) (see diagram). I use the Arm_Lib python library to control the servos with a custom script. One of the first lines is self.addr = 0x15 i think if i change that i may be able to use pwm servo interface rather than bus servo interface. Only docs for the expansion board are attached and at the link above.

NVIDIA Jetson Hardware

• [ X] Jetson Nano 4gb Other:

L4T / JetPack Version Package: nvidia-l4t-jetson-io version: 32.4.4 - 20201016124427

** Software version** python 3.8 ubuntu 18.04

To Reproduce ./installServoKit.sh

Expected behavior a bunch of errors

Additional context I am using yahboom dofbot expansion board connected via 40 pin ribbon cable to jetson nano4gb. I want to drive a servo(using python) using pwm servo interface rather than the default bus servo interface.
