Introduce StationPi CM5

StationPiCM5 is a newly designed six-in-one multifunction CM5 audio base adapter PCB. It enables the development of even nice and more professional digital audio reclocker/streamer/DDC/DAC projects by making use of the most powerful RaspberryPi CM5.

Features and Specifications 

  1. Carefully designed dedicated  CM5 Audio Base adapter
  2. High performance RPi 5V low noise filter/cleaner (Power from GPIO) 
  3. Ultra-low noise 3.3V/2A power supply for audio clean side. Output Noise:          3.3uV RMS (10Hz-100KHz)
  4. EMI shield plate
  5. Power management
  6. Soft power button

Connectors, Switch and Button

J1: GPIO socket to connect to the CM5 IO board

J2: GPIO connector between CM5 and audio HAT such as a FifoPi

J10: Dedicated and independent GPIO connector to install pure audio HATs on the left side. J10 will be 100% isolated from J2 and any other sections of the StationPi CM5. J10 is optional but needs connecting U.FL and other cables to J11-J14 when use.

J15: USB-C 5V power input. High quality USB power adapter such as Anker or UGREEN 65W or higher are highly recommended. Though they use private PD protocol, the RaspberryPi official 45/27W USB power adapters can also be used by StationPi CM5.

J4, J5: Low-noise 3.3V output (Switched)

J3: Optional 5V Input/Output

Works as output (unstitched) when feed 5V power supply to J15

Or, as 5V input (with polarity and over voltage protection) if J15 is unconnected.

J8: Power good signal, can be used for sync ON/OFF control of external power supplies

J9: Soft power up signal (Optional, need software to enable)

J6: Can be connected to CM5 IO J2 power button pins to use S1 as CM5 power button 

J11,J12,J13,J14: U.FL SCK,LRCK,DATA and I2C connectors when use J10 as independent audio GPIO.

S2: ON/OFF switch for both CM5 5V and lower-noise 3.3V power supplies

S1: Optional power button (J6 need to be connected to enable)

Power supply Noise Measurement Results

  1. Noise density of the input standard high quality 65W USB-C 5V power adapter @1A output current.
  2. Noise density of the StationPi CM5 5V output for CM5 after noise filter @1A output current with the same USB-C power adapter as input.
  3. Noise density of the StationPi CM5 Linear Ultra-Low Noise 3.3V output @500mA output current with the same USB-C power adapter as input.
    -125dBV (0.56uV) @ 5Hz
    -138dBV (0.13uV) @ 100Hz
    -144dBV (63nV) @ 1kHz
    -160dBV (10nV) @ 90kHz
Note:

1.  To use USB power adapter, please connect it to J15 of StationPi CM5, not to the CM5 IO board.
2. The side-mounted LEDs are located at the edges of the StationPi CM5, please handle with care to avoid damage from impact or dropping.
3. The StationPi CM5 incorporates a powerful TVS Diode to protect the CM5 and all connected PCBs from damage caused by overvoltage or reverse polarity power supply. If the 5V input voltage ( from J15 USB or J3 ) exceeds 6.4V or is reversed, the TVS protection activates to ensure the safety of all PCBs. However, if the overvoltage or reverse condition persists, the TVS may not recover properly from the protection mode. In such cases, LEDs D8 and D2 will not light up or keep flashing even when the correct power supply is restored. If this occurs, the TVS D4 (located behind connector J3 on the back side of the PCB) must be replaced. The part number is SMCJ5.0CA. Note that D4 is bidirectional, so polarity does not matter when installing the replacement.
