## Questions & Answers

**Q: Clock speed?  Chipset?**
A: The chipset is in the description, it is the FTDI FT232rl, it is internally clocked so there is no easy way to know what it is set to.  If it helps I have personally run this unit at 115Kbps

**Q: The ESP8266 Wi-Fi chip uses 3.3 vdc. With switch set to 3.3 volts on the programmer can you directlyTx and Rx to the ESP chip without level shift?**
A: Yes.  I've been programming numerous ESP8266 versions with this.  No level shifting required

**Q: Can it be powered via vcc and via usb at the same time?**
A: While I have never done it, I only use it to program pro minis, it should be fine as long as it is under 500 mah, matches the 3.3/5v and shares the ground. I still think it would be best to program it only under USB power if possible though. At worst the fuse is tripped but that's what it is there for. If you ordered from me and do this, let me know your results. If it damages your board, please get in touch to get a no cost replacement.

**Q: Gave up. can anyone get this to work? even tried with term emulator and known=-good mcu.**
A: I found these only sort ot work with usb3.0. You can read, but not write. Don't forget some coms require rx and tx to flip. Rx of ftdi to tx of device... like with uart.

These work great. This is the second one I've bought.

### ⭐⭐⭐⭐⭐ It does work!
*by G***U on November 18, 2017*

It could be faked FTDI chip as others claimed. But, to be fair, it does work for its purpose. I used it to flash several ESP8266 based SonOff devices many times. There are two things I learned in the process though I would like to share: 1) This chip could output 3.3v or 5v. It is on 5v when I got it. You can switch to 3.3v using the jumper close to the output pins. If you are flashing ESP8266 devices like me, make sure you switch to 3.3v first! 2) Make sure the USB cable you use to connect this to your computer is a data cable, not a charging only cable. This was the reason it did not work for me at first.
