I have a rpi4 and have successfully replicated the project listed here using the eTape sensor (etape tutorial) I am satisfied with the performance using long breadboard and T-cobbler. In order to make my setup more compact I purchased the pi-EZ connect board. When I connect all the jumper cables; the sensor no longer works and I get a 3.3V reading from the sensor which does't make sense. It should be within 1.0-1.8V in order to convert into a sensible volume. The sensor does require 3.3V to run; and I'm just getting that value back? I double checked the jumper cables and even tried different cables; but I can't get it to work. I re-assembled with the t-cobbler and breadboard and it works. Not sure if the pi-ez board is bad? The little circuit chip on the right in the photo is the MCP3008. Would like some suggestions or advice on what troubleshooting steps to take from here. Thanks.
