Both items faulty, Sda pins on both are permanently grounded. Hex address pin on pcb artwork goes to gnd, not to the select pin. I removed this and tried different hex address, but sda pin still permanent low / gnd. Run i2c scan tool and will not detect device due to sda line fault. Contacted seller03/12/20 but no reply. Bought a unit from UK, slightly different artwork and works ok.
Thanks a lot, working perfect! Greetings from Germany! Fast delivery!
