Product WRL-10822 |

I’m trying to figure out page 5 of the datasheet. Are the resisters that it’s talking about on the shield, or should they be installed externally. My reading of it is that they are on the shield (the default configuration), which would fix pins 13, 15, and 18 to GPIO. Does that sound correct?
I also don’t understand the values for R8,11,17,20 (0R?).
Edit: Looking at the picture, which I can see better than the device itself ;-) It looks like the resisters are on the back of the shield. I would have to de-solder one of the 0 (0 ohms?) resisters on the back to add an additional sensor input. I’m assuming these resisters are intended to make the sensor inputs 3.3V compatible, whereas the reference manual states a 1.2V max.
No public wish lists :(
