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.
