Here we will define the pins used for our drivers, endstops, heaters, fans, probe, etc. Refer to the table of pin assignments from Part 1.

X as Driver_0, Y as Driver_1, Z as Driver_2, E as Driver_3

X Endstop = io5.in, Y Endstop = io6.in, Z Endstop = io2.in.

Heater0 (bed) = OUT0 and TEMP0. Heater1 (hotend) = OUT1 and TEMP1.

Fan0 = out3, Fan1 = Out4, Fan2 = Out5, Fan3 = Out6 for the LED strip.

Z-Probe will be a BLTouch, so for Input Pin choose io3.in, leave Modulation Pin unassigned, and PWM Control Channel as io3.out.
