Power Supply

LattePanda Mu x86 compute module features a wide voltage input design. To ensure stable system operation, strictly adhere to the following design specifications.

Voltage Requirements

Parameter Min Typ Max Note
Recommended Input 9V 12V / 15V 20V Preferred operating range
Absolute Maximum Input 7.6V - 22.3V Exceeding limits triggers UVLO or OVP
Voltage Ripple - - 200mV Peak-to-Peak

  • Without an eDP display, for maximum compatibility and safety, maintaining the input voltage between 9V - 20V is strongly recommended.

  • ⚠️ With the eDP display, the maximum power supply voltage is limited by the eDP display.

    • In the hardware design of the LattePanda Mu compute module, the power supply for the eDP display's converter is directly to the system power rail without any voltage step-down circuit.
    • So if your design includes an eDP display connected to the LattePanda Mu compute module, the overall system maximum voltage will be limited by the eDP display's converter maximum input voltage.

Connection Guidelines

Pin Definition

Pin Name Pin Number Note
VIN 251,253,255,257,259,
250,252,254,256,258,260		 Main Power Input;
Recommended Range: 9V ~ 20V

Since there are many GND pins, they are not listed individually here; please refer to the LattePanda Mu Pinout Documentation.

Pin Connection

To minimize impedance and support high current, ALL VIN pins must be connected to the positive power rail, and ALL GND pins must be connected to the negative power rail.

Power Budget

The power supply design must account for sufficient power headroom. Excluding power consumption from carrier board peripherals (e.g., high-power USB devices, PCIe cards), the minimum power requirements for the compute module itself with default BIOS firmware are:

  • LattePanda Mu (Intel N100): > 10W
  • LattePanda Mu (Intel N305): > 15W

The values mentioned above represent minimum limits and may impact performance. It is recommended to allow for at least a 50% margin.
