"This is the populated pcb with everything you need to make use of the MLX90621 IR Array except the array itself. You may purchase the MLX90621 from Mouser or Digikey. It is an expensive part, so I am offering only the populated pcb with through holes for mounting the MLX90621, 4K7 pullups on the SDA and SCL pin pads, and an NCP161AMX25 450 mA, 2.5 V LDO with bypass capacitors on the VDD input."
Not sure how I could make it any clearer.
If you aren't happy with your purchase, please send me the product and I will refund your money.
Make sure you read the fine print on the board and consider the close-up photo on the web page as serving a decorative purpose at best. If you hook them up accordingly, you'll fry the mics, ask me how I know. As for the product itself, I have to give it the benefit of the doubt, since the seller refused to make me whole and put the blame on me, so I have no way to test it anymore. Edit: following me writing this review, the seller now updated the documentation to reflect the ICS-43432 based design.
We are using this board with a Teensy 3.2 and are having problems. It works sometime and does not work sometimes. We have checked all the connections and it seems to be fine. Any help or pointers would be great. We are planning on testing it with just an arduino - will post the results (I would like to change the ratings once we get it working)
