Hi @asavvin

Other than 3.3V and GND there aren't any fixed set of pins for that, it's whatever the code you use expects.

For example in my case I used these

RST = Pin('P19')
DC = Pin('P20')
BUSY = Pin('P18')
CS = Pin('P4')
CLK = Pin('P21')
DIN = Pin('P22')

But you'll need to use whatever your code is set to.
