Custom Fan Board Setup Instructions

To set up the custom fan board, follow these steps:

  1. Connect J4.4 on the Intel® MAX® 10 Development Kit to point A on the custom fan board. Point A connects to the gate of 2N7000.
  2. Connect J4.5 on the Intel® MAX® 10 Development Kit to GND on the custom fan board.
  3. For the 12-V DC-fan connection, connect the red and black lines. You must add a supply line to the fan.

To set up the PMBus connections between the Intel® MAX® 10 Development Kit and the ED810X+FDMF5820 Kit, follow these steps:

  1. Connect the PMBus lines between the Intel® MAX® 10 Development Kit and the ED810X+FDMF5820 Kit.
  2. Connect the PMBus on each of the ED810X+FDMF5820 Kit in a daisy chain. For more information, refer to the ED810X+FDMF5820 Kit Daisy-Chain Connections table.
    1. Connect SCL and SDA lines from the first ED810X+FDMF5820 Kit to the second ED810X+FDMF5820 Kit.
    2. Repeat this step for the second and third ED810X+FDMF5820 Kit in the daisy chain.
  3. Connect the VOUT on the ED810X+FDMF5820 Kit to the Intel® MAX® 10 Development Kit (J20 header) to monitor the voltage level of the power module using the Intel® MAX® 10 ADC. For more information, refer to the ED810X+FDMF5820 Kit Connection for VOUT figure and VOUT to J20 Header Connections table.
CAUTION:
The analog channel of the Intel® MAX® 10 development kit supports up to 2.5V only. Do not provide voltage higher than 2.5V to the analog channel.
Figure 15.  Intel® MAX® 10 Development Kit Connection for the ADC Input PortYou can modify the design example if you are using more than three power modules in your design. There are up to 16 ADC channels available.

After you have the complete hardware connection for the design example, you can program the bmc.pdf to the Intel® MAX® 10 device to test the functionality of the design example. If you need to customize the design example, follow the steps listed in the Customizing Design Example section.
