MKS 3MOS - Fan expansion module

MKS 3MOS is a connection fan module. The module integrates 3 MOS control outputs, and its pins and dimensions are compatible with pluggable motor drive slots. It can be used directly by connecting to the drive slot and simply configuring the pin file. Suitable for motherboards with more than 5 axis motor drive slots.

• Size: 20.32x15.24mm.
• Power input: DC12-24V.
• MOS out current: <1A.
• Fan interfaces: 3
• Control signal:
  FAN1 uses ENABLE signal
  FAN2 uses STEP signal
  FAN3 use DIR signal
• Firmware settings: In board pins file add it:
  // If connect to E1 axis. If board's pins has FAN1_PIN, you need to start from FAN2_PIN
  #define FAN1_PIN    E1_ENABLE_PIN
  #define FAN2_PIN    E1_STEP_PIN
  #define FAN3_PIN    E1_DIR_PIN
• Command control:
  Open FAN: M106 P*S255   // * 1, 2, 3, ...
  Close FAN: M106 P* S0   //   * 1, 2, 3, ...
  //Close FAN, M107 command is not recommended.
