Hi folks,
I purchased the RTD data acquisition raspberry pi hat back in 2019, got sidetracked, and am now finally back at it. The board is labelled 5.1.
I've never used a Pi hat before, so I'll apologize in advance if my questions are pedestrian.
1. I plugged the hat directly onto the gpio pins of a raspberry pi I have lying around, which is being powered by a POE-splitter from a POE switch. Does the hat need a separate power supply too, or does it somehow draw power from the gpio bus? If the hat needs a separate power supply, I see a pair of connection points at the upper right of the board labelled 5V and GND, does that imply I need to somehow splice a pair of raw wires from a 5vdc power supply to connect to those connection points on the board?
2. I have some PT100 RTD's I intend to use for testing, with 2x red wires and 1x blue wire. I strongly suspect the RTD is between the blue and either of the red wires, and I should connect it to the hat connection points in that manner. Correct?
Thanks!
