PiBot V5.77 Carrier reference files

The YAML below is an I/O test configuration. It deliberately enables many board functions so the checklist can verify them. It is not safe to use unchanged on a real CNC, laser, or spindle machine.

Before Creating Your Machine YAML

Keep an untouched copy of the test YAML for future board diagnostics.
Choose only the inputs, spindle interface, communications, and axes your machine actually needs.
Replace steps/mm, direction, acceleration, travel, homing, limit, spindle/laser, and safety settings with values verified for your machine.
If the module uses GPIO.38 for its RGB LED, move item 2 to GPIO.48 and change the Z-limit pin in YAML.

For connector details, start with the Pinout Reference.
