 The wiring is not as complex as it might look, it is just a simple transistor on each data pin to convert from 1.5v up to 3.3v for the esp32 to be able to read, I use my CNC router to create the circuit boards but this could be easily built on some strip board etc.  I tried using a level shifter board at first but I don't think it worked very well with the 1.5v levels. <br>
 Note: the transistors to convert the 1.5v signals from the caliper results in the signal levels being inverted so if you use some other method you will need to change 'invertCaliperDataSignals' to 0.  The circuit diagram I used can be seen in the PCB folder along with the files I used to create the circuit boards (Fritzing and CNC router).  To supply the lower voltage to power the caliper I just use a simple voltage divider

 Note: I am using GPIO0 which isn't ideal as it is also attached to the onboard button, but if you do not install the pull-up resistor and use a lower value resistor on the input this seems to work fine (although it can stop the hardware reset working when programming the CYD).
