Hello,
Please take a look on the BWS CAR PS V1 datasheet - https://bluewavestudio.io/resources/bws_...asheet.pdf
In case of Raspberry PI 3B the wiring will be:
PIN 2 - 5V

PIN 6 - GND

PIN 5 (GPIO 3) - STBY

Hello dear Bluewave studio team,



since I still don't know enough about the GPIO assignment of the RPI, I would like to describe my problem here:

Your script used port 3 for on/off switching of the Raspberry Pi. Unfortunately the same port is used for a HIFI soundcard as I²C bus, so there will probably be conflicts. Can I, and if so, how can I put the GPIO port on a free port. Can I change this on the installed files, or do I have to change the script before and then reinstall it?



Greetings Joachim Junker

Yes, there will be conflict. You can change the pin for shut down but unfortunately this is the only pin which can be used for wake up, due to technical restriction of the RPI.



As a solution you can implement a software I2C bus on any pair of spare GPIO. You will need to add resistor pull-ups to 3V3 on any spare GPIO you use. Try search some ready implementation.
