​​Pin Functions ( )​​

​​VDD:​​ Power Input (3.3V–5.0V). Decouple with 0.1μF Ceramic + 10μF Electrolytic Capacitor.

​​GND:​​ System Ground. Share with Controller and Magnet Bracket (PCB Copper ≥90%).

​​SCLK:​​ SPI Clock Input. Requires 4.7kΩ Pull-Up to VDD (Trace Length ≤20 cm).

​​SDI:​​ SPI Data Input (Host to Slave). Use Twisted Pair for Noise Immunity.

​​SDO:​​ SPI Data Output (Slave to Host). Connect to MCU MISO Pin.

​​CS:​​ SPI Chip Select (Active Low). Independent Control for Multi-Module Cascading.

​​PWM:​​ 12-Bit Absolute Angle Output (Duty Cycle = Angle/360°).

​​ABZ:​​ Incremental Quadrature Output (A/B Phase 90° Difference, Z Index Pulse).

​​UVW:​​ Motor Commutation Signal (U/V/W Phase 120° Difference).

​​FAQ​​

1.
​​Fixed Angle Deviation (e.g., Constant 5° Offset)?​​

→ Perform Self-Calibration: Power On and Keep Module Still for 2 Seconds (LED Stops Flashing When Complete). Ensure Magnet S-Pole Faces Module Marking Surface.

2.
​​SPI Communication Unresponsive?​​

→ Check CS Pin Independence for Multi-Module setups (Default Address 0x40). Add 4.7kΩ Pull-Up Resistors to SCLK/SDI/SDO Lines.
