I was wondering if I could use some of the pins on the OpenRB-150 for another application (i.e. FSR sensor at the end of the dynamixel’s). Do you know which pins if any would be available to use for non-dynamixel stuff?
Adafruit has a nice tutorial for FSR and Arduino boards such as the OpenRB-150:
It looks like that any analog pin available is OK to use:
As stated by Roboteer, all of the analog pins are available for use. In fact, for the OpenRB-150, all of the pins on the headers are available for use with MKR format Arduino accessories, as the DYNAMIXEL ports use a dedicated serial port.
More information regarding the specific capabilities of the pins is available on the OpenRB’s eManual Page.
