Re: Group Buy: CH341A Programmer
I'm thinking of cases where the patient PCB is dead and its "ROM" contents need to be transferred to a donor PCB. This frequently happens in HDD data recovery. In such cases the programmer would need to power up the PCB.
As for contention issues, that happens too. In such cases the data recovery professionals swap the actual ROM, but I've always wondered whether there is a simple in-circuit solution. Most of these people are programmers or IT "techs", so their knowledge of electronics is essentially zero. Basically they are just head swap mechanics and ROM jockeys, so getting them to try anything is often fruitless.
