I did manage to find some example python programs for this hat, one of which was for testing 2 hats stacked.
In it is this bit of code
Code: Select all
# bottom hat is default address 0x6f
bottomhat = Raspi_MotorHAT(addr=0x6f)
# top hat has A0 jumper closed, so its address 0x61
tophat = Raspi_MotorHAT(addr=0x61)
so that tells us we need to close the A0 jumper for the second hat, but there is no detail on were or how which is why I asked for some good quality pictures.
