Hi, Any1 have experience with this usb to TTL 6 pin converters? I just want to know if I have a dodgy one that I bought from Ali or normal behaviour.
Doesnt seem right. I have it plugged to a powerbank, following voltages read from pinout, without any jumper link.
5v = 5.3 Vcc = 3.9v 3.3 = 3.2v Tx RX = 3.9v
If I use jumper link from 5v to VCC, then tx RX = 5.3v, if I jumper link VCC and 3.3, RX and tx = 3.9v.
Thanks for reading

"On certain 3.3 V devices, any voltages above 3.6 V will cause permanent damage to the chip. " Well thats not good. I guess I have my answer 3.9v is high 🤷
