I am toying with the FTDI device, and it is very easy to work with, but not cheap.
I looked online at Prolific, but the horror stories I have heard about the devices makes me apprehensive.
There has been mention of the CH340x family and I can get those from Octopart, and the price is certainly right, but again, I know little about the company and not much about Octopart. The only website I can find for the CH340 is:
But that goes nowhere. The other odd thing is that the USB pins on the part connect DIRECTLY to the USB pins of the connector I will supply where I am used to seeing a couple of series resistors.
SO, Prolific is out as far as I am concerned. The FTDI is a little pricey, and the CH340 is the dark horse in this race.
Can anyone shed light on experiences with OCTOPART, and/or the CH340 part? I can live with the translated datasheets for it and if the vendor actually delivers great. My only concern is I am going to need possibly 1000 of these and I do not want to design the board for them and end up screwed.
