Review on Enhance Your UNO R3 with the HiLetgo 5V 4 Channel Relay Shield: Efficiently Control Four Channels by Jose Perry

UPDATE: The seller contacted me to see if I need a replacement but I've already moved on to another solution. Glad you followed them - plus 1 star for that. I can say that the item pictured with curved pins is an accurate representation of what you will receive. Mine had a couple of bent pins, which is a bit understandable, but those pins also had solder where it shouldn't be, and all the hand-soldered connections on the underside of the board had solder residue that shouldn't have. be there too. Because of this poor build quality and quality control, I can't be sure if the item is working properly or the components are good, so I returned it.
