Please make sure you fix the 3.3 V output if you get that device. Most revisions have a PCB layout issue that will output 5V even in 3.3 V, which has bricked stuff before. There are many ways to fix it, one trace cut and one jumper is how I did it. https://libreboot.org/docs/install/spi.html#do-not-buy-ch341a https://libreboot.org/docs/install/spi.html#do-not-buy-ch341...

I think all of them sold nowadays have this fixed but yes, absolutely worth checking.

  The kit I bought 10 months ago had the issue. Luckily I was only unable to read some chips, and did not fry anything. Definitely check it before using it.
