Thanks @martinayotte, i give it a look in these days, my last attempt seems that the relais was always on, also with low signal. Thank you so much

This is my module

Hi and good evening. Can I have some support about wiring? you attach to the SPI1 in the pinout? Should i reconfigure the bin file using FEX to use the SPI1 in python? THANK YOU

Thank for this, now i know why it does not work. But it still not clear. i change this: { "STATUS_LED", SUNXI_GPA(15), 2 }, to this { "STATUS_LED", SUNXI_GPA(17), 2 }, then i reinstall everything with python setup.py install but it seems to be too fast, i think it did't recompile my mod. Do i missing something? THANK YOU!
