Protective diodes for relays - S1L - 05-20-2025
Hello. In the KC868-A2 circuit, the protective diodes D9, D11 are connected in parallel to the transistors, not the relay coils. Is this an error or a feature of the circuit?

yes, this is a bug of KC868-A2 v2.4 PCB. KC868-A2 v2.5 and KC868-A2v3 PCB have fixed this bug.
