I have been enjoying the TouchDro I installed a few months back. Works great! Always wanting to take it up a notch I have been working on installing the hardware for the Tach feature. I have the board with the MicroB connectors and plan on using a Sainsmart Hall effect sensor module. I have machined and installed a ring with 8 magnets on the lathe. My electrical skills favor wiring a house and not so much micro circuitry so I need help on making the connections from the Sainsmart to the MicroB board. The Sainsmart module has solder terminals for a plus, negative, AO and DO. The Touchdro board has Tach labeled next to four unlabeled solder terminals. Which terminals do I use and which connection goes to what?
