Anyone have 1 or more of the external sensors?


I'm trying to determine the feasibility of building my own external sensors. This thread gives the pinouts of the 3.5mm jack:

Sleeve 1 gives the ID of the external sensor. I imagine that it is just a resistor value. If you have a multimeter and a sensor could you please measure and post your findings here?

The ID is probably measured against 3.3V (tip) or GND (ring 1) as shown in this diagram:

  • I believe their is a chip with a unique id on each of the sensors so the twine can identify the sensor. This is also needed as one may have multiple breakout boards with different configurations and twine knows which is which once configured. I think this was in one of their posts about the breakout boards at kickstarter.
