Yes it's more expensive, but compared to the days I spent thinking I had a problem with my code and it was just a driver change that broke everything, trust me, in my case, worth it (and it was 2nd time of driver problem, so we'll have again and again in the future). By the way, on the link I posted, they have on board regulator and 5V/3V3 switch that make them suitable for powering ESP modules that the other can't do seriously Love them
Anyway, any chinese FTDI chip claiming FTDI original are fake, trust me I've got 10, all fakes and I even built my own with chinese FT232 chip bought on ebay, and guess what, they're also fake.
But any other cheap chip other than FTDI will works
This one should do the trick
