PETOI Bittle X - additional servo's
Hello, I am trying to connect a hacked 5V servo to the petoi bittle x. How can I achieve this? I've tried plugging it in to the 2 TX ports on the grove bord and adding servos in the src arduino folder, but it does not work. Does anyone have experience with this

What's the type of the servo? Is it PWM or serial servo?
If it's a regular PWM servo, you can plug it in the unused PWM servo pin. There are 12 PWM servo pins and only 11 are used. However, the servo pins are powerd at 8.4V, so you will need to add a voltage divider.
Alternatively, you could use the Tx2 pin. But you will need to modify the PWM pin declaration in OpenCat.h. Then in the controlling part, call jointIndex 3 to control it.
