Possible Solution:

• Use JST connector instead of plugging the waveshare HAT directly into the raspberry pi (see table below)
  • try switching to the wire JST connector and plug the black dupont connectors directly into the GPIO headers of the PI (see table below)
  • See pinout.xyz for help locating the proper GPIO pins
