It seems identical to this device’s schematics.

The only difference being D+ and D- not being connected, since these are used for legacy protocols (such as USB-BC). I used it to connect a CP2104 instead.
this is what i found in the datasheet, i think you need to be careful with the choice of resistor you use for pin CFGI, pin 9. So it should be able to work with voltages ranges of 9v, 12v, 15v
Thanks, but as far as I understood, that’s only relevant for resistance configuration mode. Typically 10k pull-ups or pull-downs are used for level configuration mode.

I did refer to the datasheet when designing my board.
