Hi

I am having trouble connecting a FT2322HL to my ESP32. I have followed instructions from the site which said

GPIO12 - AD1 (TDI)
GPIO15 - AD2 (TDO)
GPIO13 - AD0 (TCK)
GPIO14 - AD3 (TMS)
GND - GND

Using two USB leads on my PC and the device was detected.

Code: Select all

My problem is I believe I have blown up two of these. When plugging in the PC I get.

I believe it could be caused by the socket jumper cables flipping off the connector on the FT2232H and maybe touching the 3V3 or the VCC pins but this is only a guess from a novice. There are five wires required and they are very easy to come off when plugging the USB back in.

With two board blown I would be keen to understand how people would normal do this. Or if I am doing something wrong and it is not the leads. I am new to this so do not know the best approach but happy to learn from people who do.

Question from again, a novice are
1/ Is there a better way to connect five wires more securely
2/ Is there a standard way to guard the live pins aside from insulation tape
3/ Can I still connect without the usb via another usb board I have.
4/ What is the best site to buy parts from as I am in NZ
