SparkFun FTDI Basic Breakout - 3.3V Development Tool with USB Mini-B Connector Save Space and Money in Your DIY Electronics Projects Pinout of This Board Matches The FTDI Cable

Worked a treat! Plugged in, no driver issues, win7 64b. Tried the ch340 and it never worked.The ftdi was no troubles.

very good product.sucess to flash SPI device quickly a lot of timesI recommend

works great, just not sure why are these things so expensive!

I'm using this with my Arduino Pro Mini 3.3V (also from SparkFun). It worked perfectly. The drivers loaded automatically. It allows you to program the Arduino and also monitor the serial output.

Great product worked great unlike the other one I ordered for cheap, turned out to have a counterfeit chip that the new drivers brick on connection. Not this one though authentic and fully functional.

Using this for arduino mini pros, does the job great. Plugged right in and works great to my mac with the FTDI driver.

Works exactly as expected for ESP8266 devices that require 3.3v instead of 5v.

This is part of a project one of our techs is developing so I can not say more about it then it must have done the job or I would have heard about it. The part that was ordered was the correct part and shipped quick.
