For a school project we are making a self-driving rc car. for this we use a jetson nano (with ubuntu 18.04) which controls a pwm driver (pca9685). This will send steering and throttle commands to the ESC and servo motor.

For as far as we now we need the busio and board libs from adafruit-blinka for controlling the pca9685.

While installing the adafruit-blinka lib, we get the following error:

module 'adafruit_platformdetect.constants.chips' has no attribute 'JH71x0'

What do we do?

We already managed to install this once on a Ubuntu 20.04 version but it won't install on this one. The reason we went back to the 18.04 version is because we couldn't get our self driving model (an onxmodel) to run on our Ubuntu 20.04 system.
