Each driver uses Step, Dir, and Enable pins. No UART/SPI connection.

Note: V2.2 board has only MIN endstops; MAX ends are not populated. Note: V2
The V2.2 board has only one Z-motor driver (Z-STEP and Z-DIR on PB3/PB4). The diagram reveals two parallel 4-pin JST ports labeled Z and Z2. Important: These are wired in parallel, not independent.
For true independent dual Z (auto-alignment), you need a board with dual Z drivers (e.g., BTT SKR 2). The V2.2 diagram cannot support Z2_STEP pin.
