To add Ethernet to the Raspberry Pi CM4, you will need to properly connect the Ethernet signals between the CM4 and an appropriate Ethernet PHY. The CM4 provides signals typically required for Ethernet connectivity, such as TX, RX, and control signals.
Based on the project components provided, let's connect the relevant Ethernet pins to a standard Ethernet PHY (e.g., Microchip's LAN9514 or Broadcom BCM54213). Here are the steps and connections you need to make:
Steps to Add Ethernet
  1. Choose an Ethernet PHY: Select an Ethernet PHY chipset that supports the required speed (10/100/1000 Mbps) and has the necessary interface.
  2. Make Connections: Connect the appropriate signals between the CM4 and the Ethernet PHY.
Typical Connections
Assuming you're using a typical Ethernet PHY, here are the connections:
Ethernet Tx/Rx Differential Pairs
  • Transmit Pair 0:
    • Connect CM4:ETHERNET_PAIR0_P (Pin 12) to PHY:TXP0.
    • Connect CM4:ETHERNET_PAIR0_N (Pin 10) to PHY:TXN0.
  • Receive Pair 0:
    • Connect CM4:ETHERNET_PAIR1_P (Pin 4) to PHY:RXP0.
    • Connect CM4:ETHERNET_PAIR1_N (Pin 6) to PHY:RXN0.
  • Transmit Pair 1:
    • Connect CM4:ETHERNET_PAIR2_P (Pin 11) to PHY:TXP1.
    • Connect CM4:ETHERNET_PAIR2_N (Pin 9) to PHY:TXN1.
  • Receive Pair 1:
    • Connect CM4:ETHERNET_PAIR3_P (Pin 3) to PHY:RXP1.
    • Connect CM4:ETHERNET_PAIR3_N (Pin 5) to PHY:RXN1.
Control and Miscellaneous Signals
  • LED Signals:
    • Connect CM4:ETHERNET_~LED1 to PHY:LED1.
    • Connect CM4:ETHERNET_~LED2 to PHY:LED2.
    • Connect CM4:ETHERNET_~LED3 to PHY:LED3.
  • Clock and Sync Signals:
    • Connect CM4:ETHERNET_SYNC_IN to PHY:SYNC_IN.
    • Connect CM4:ETHERNET_SYNC_OUT to PHY:SYNC_OUT.
Power and Ground
  • Power Pins:
    • Ensure your Ethernet PHY is powered appropriately, typically needing a 3.3V or 1.8V power supply.
    • You can derive this from the CM4_3.3V(OUTPUT) or CM4_1.8V(OUTPUT) pins if your PHY supports these voltages.
  • Ground Pins:
    • Connect CM4:GND__# to the ground pins of the Ethernet PHY.
Example Connection List
  • Connect CM4:ETHERNET_PAIR0_P to PHY:TXP0.
  • Connect CM4:ETHERNET_PAIR0_N to PHY:TXN0.
  • Connect CM4:ETHERNET_PAIR1_P to PHY:RXP0.
  • Connect CM4:ETHERNET_PAIR1_N to PHY:RXN0.
  • Connect CM4:ETHERNET_PAIR2_P to PHY:TXP1.
  • Connect CM4:ETHERNET_PAIR2_N to PHY:TXN1.
  • Connect CM4:ETHERNET_PAIR3_P to PHY:RXP1.
  • Connect CM4:ETHERNET_PAIR3_N to PHY:RXN1.
  • Connect CM4:ETHERNET_~LED1 to PHY:LED1.
  • Connect CM4:ETHERNET_~LED2 to PHY:LED2.
  • Connect CM4:ETHERNET_~LED3 to PHY:LED3.

  • Connect CM4:GND__# to PHY:GND.
  • Connect CM4_3.3V(OUTPUT) to PHY:VDD33.
Make sure to refer to the datasheet of the specific Ethernet PHY you are using for pin names and additional required connections (such as MDIO/MDC for management if needed).
Feel free to correct any assumptions or provide more details about the Ethernet PHY you plan to use so I can give you more specific instructions!

How to connect VL806 to this module to have 4 USB3?
2y

copilot

To connect the VL806 USB3.0 hub controller to the Raspberry Pi Compute Module 4 (CM4) to provide four USB 3.0 ports, you need to correctly wire the High-Speed Differential Pairs and control signals between the CM4 and the VL806 controller, and also ensure proper power supply connections.
USB 3.0 Overview
USB 3.0 adds SuperSpeed (SS) signals to the USB 2.0 interface, so each USB 3.0 connection requires additional differential pairs for the SS data lines.
Assumptions
  • You have a VL806 USB 3.0 hub controller.
  • You want to connect it to the CM4 to provide four USB 3.0 ports.
Necessary Connections High-Speed Differential Pairs (SuperSpeed TX/RX)
  • USB_SS_TX/RX:
    • Connect CM4:USB_OTG_ID to VL806:OTG (if needed for OTG pin).
    • Connect CM4:USB_P to VL806:USB3_SS_RX_P.
    • Connect CM4:USB_N to VL806:USB3_SS_RX_N.
    • Connect VL806:USB3_SS_TX_P to the USB3 SS TX pair.
    • Connect VL806:USB3_SS_TX_N to the USB3 SS TX pair.
Control Signals
  • Power Enable:
    • If VL806 has a power enable pin, connect it to a GPIO pin on the CM4 for control.
  • Reset:
    • Connect VL806:RESET# to the CM4:RUN_PG pin or another GPIO capable of controlling reset.
  • Clock:
    • Connect a reference clock (usually 25 MHz or 48 MHz) to the VL806 as specified in its datasheet.
USB2.0 Data Lines
  • USB_DP/DM:
    • Connect CM4:USB_P to VL806:USB2_DP.
    • Connect CM4:USB_N to VL806:USB2_DM.
Power and Ground
  • Power Supply:
    • Ensure the VL806 is powered correctly according to its voltage requirements (usually 3.3V or 1.8V).
    • You can supply 3.3V from the CM4_3.3V(OUTPUT) pin or use an external power supply.
  • Ground Connections:
    • Connect all ground pins on the VL806 to CM4:GND to ensure a common ground.
Example Connection List
  • Connect CM4:USB_OTG_ID to VL806:OTG (if required).
  • Connect CM4:USB_P to VL806:USB3_SS_RX_P.
  • Connect CM4:USB_N to VL806:USB3_SS_RX_N.
  • Connect VL806:USB3_SS_TX_P to USB3 port TX_P (external connector TX+).
  • Connect VL806:USB3_SS_TX_N to USB3 port TX_N (external connector TX-).
  • Connect CM4:USB_P to VL806:USB2_DP.
  • Connect CM4:USB_N to VL806:USB2_DM.
  • Connect the VL806 power pins to the CM4_3.3V(OUTPUT) pin.
  • Connect all ground pins (e.g., CM4:GND__#) to the ground pins on the VL806.
  • Optionally, connect VL806:RESET# to CM4:RUN_PG or another GPIO pin for reset control.
Power Considerations
Ensure that the power supply section of the VL806 is properly designed to handle the current requirements of the USB3 ports, especially if all four ports will be active simultaneously.
Clock Input
Check the VL806 datasheet for the correct crystal or clock input specification and ensure the appropriate circuitry is in place to provide this clock.
Verify Connection
It's critical to verify all connections against the specific datasheet of the VL806 and the CM4 IO board schematics. This ensures that signal integrity and power requirements are adequately met.
Feel free to reach out if you need more detailed help with any specific aspect of this setup!

copilot

To add the VL806 USB 3.0 hub controller to the schematic with the necessary connections to the Raspberry Pi Compute Module 4 (CM4), here are the steps and connections provided in a detailed manner. Below is a connection list to guide the additions.
VL806 USB 3.0 Hub Controller Pinout (Assumed)
For this example, let's assume the following relevant pins for the VL806:
  • VL806:USB3_SS_RX_P and VL806:USB3_SS_RX_N are the SuperSpeed receive differential pairs.

@copilot how much power does it require
2y

copilot

The Raspberry Pi Compute Module 4, at maximum usage, typically consumes around 3 - 5 watts of power. However, the actual power consumption may change based on the utilization of the CPU, RAM, GPU, peripherals and other components.
In terms of the voltage requirements, the Compute Module 4 typically requires two input voltages:
  1. 5V: This is the main supply voltage for the module. It is generally used to power the I/Os and the HDMI interface.
  2. 3.3V: This is used to power the system ICs such as the main processor/RAM, the internal PHYs for the Ethernet and USB, etc.
However, the general recommendation is to closely follow the power requirements specified in the detailed technical datasheets by Raspberry Pi Inc. for the specific variant of the Compute Module 4 that you're using. Please correct me if I made a wrong assumption about your module.

I'm sorry for any confusion. Concerning the Raspberry Pi Compute Module 4, it is available in different variations. The eMMC (flash storage) capacity can vary from none (Lite version) to 8GB, 16GB and reaching up to 32GB. I would advise checking the exact specifications of your particular model to determine the exact eMMC capacity.

Como asistente de IA especializado en diseño eléctrico y esquemas de PCB, no estoy diseñado para proporcionar una gran cantidad de detalles sobre la responsabilidad social empresarial (RSE). Sin embargo, puedo decirte que la RSE se refiere a las prácticas empresariales que tienen en cuenta el impacto social y ambiental de la empresa. Esto podría abordarse en el desarrollo de hardware electrónico y PCB asegurándose de que los componentes utilizados son sostenibles, los procesos de fabricación son éticos y se minimiza el desperdicio, entre otras consideraciones. Por favor, consulta a un experto en negocios o ética para obtener una descripción más detallada y un asesoramiento más específico.
