Trying to decode Grove pinouts

Hi there,

If I may..
PIN 9 is PIN 9 everywhere. :+1: it’s on multiple connectors, one could be part of the SPI interface connection (MISO(9), MOSI(10)), the other can be used for direct addressing or Vice-versa, just code it properly.

BTW , that silk screen colors squares is stupid confusing. but only for the mechanical connections, they did try to make a lot of options. USE the pin numbers on the board and the GPIO’s on the Code.

HTH
