03/08 - Using Datasheet from link above, constructed the circuit (without Vt) and got data on the serial monitor and plotter. I don't have an ipad to annotate. Op-Amp used is TL071CP

Purple wire is from one + rail (3.3V)
Yellow wire is from Vout in Op-Amp,6 to Vsys (39) on raspberry pi pico.
Green wire connected from 3+ to ground
Connected random resistor value Rf from 2- to 6out on opamp
small red wire - Vcc+ 5.5V from 7 opamp
orange wire from 4 to GND opamp.

Update the reference resistor to 10 kOhm. Can't find the force sensor arduino code in the github repository anymore.

Connected board to voltage supply and drive voltage - got something but it seems like the force sensor response time is not always immediate.
