I’m attempting to order the sensor board through Seeed, and there’s been a problem identifying the final component in the .csv, labelled U1 and QRE1113GR. I have attached the error message I got below. Seeed cannot identify the part, and it’s name is not listed anywhere so I could not find a substitute. Is there a comparable component on Seeed that I could substitute in easily? EDIT: Looking through the Excel sheet, I found the component through Mouser. I will try to add that through the purchase link and hope that works for the PCB board.
Secondly, the DC/DC converter is no longer available on Seeed with the same specs. Is this one from Tindie an appropriate substitute?
