Customer questions
Q ![Canada]( "Canada")
SeanCan you confirm the chip is the SR04M (any version variant). Should be a dumb question but have received variations of the SR04T from other suppliers. I haven't been able to get the SR04T chip to work in my application but the SR04M consistently functions fine. I've struggled to determine the reason why as the actual sensors seem interchangeable though the chips aren't. This problem was very frustrating to troubleshoot and ultimately wasn't fixable with my abilities. I'd like to ensure the chip to be consistent if I go with this you for supply.
