The 8×8 Monochrome Matrix Finished¶
Published on 2017-04-19 in D1 Mini Matrix Deluxe Shields.
Well, almost. There is going to be one more version of the PCB, because_of course_I swapped one of the rows with one of the columns of the matrix.
You can also see that one of the rows has a cold joint in there, but that was easily fixed.
I also wrote a MicroPython library for this matrix, which is available at https://bitbucket.org/thesheep/micropython-is31fl3728/src
I will still need to update it to reorder the rows and columns to fit the reality – but I will do that once I get a final working PCB.
