ch341a programmer with a clip attachment. That's basically it. A 10 USD investment. No soldering unless flash chip is SMD.

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.

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