Before looking into the I2S implementation, I'm thinking that I'm getting more confident in creating electronic library components now and should actually make the BLDC motor pad instead of mentally remembering its existance.

And there we have it. I've also added values to the 3 sense resistors. Also, I'm not sure why the order was "U, W, V" in the EasyEDA schematic and not "U, V, W". I'll also have to check if 10K resistors are fine or if I should lower them to 4.7K.
