  • I’m a novice and experimenting with this using just an Arduino before hopefully using it to connect my Arduino to my Raspberry Pi. When I connect 5v to RXI I measure 1.5v at RXO rather than the expected 3.3v. I still measure the 1.5V at RXO even if I don’t connect 3.3v to LV. I have the Arduino 5v connected to HV, Arduino 3.3v to LV, both GND to Arduino Ground, and one of the Arduino digital pins connected to RXI that I’m setting High/Low in the sketch. I’m using a multimeter to measure the voltage between RXO and the Arduino ground. Could I have damaged the board by using it incorrectly or maybe I’ve soldered it badly? Thanks for any help or suggestions.

No public wish lists :(
