StationPiCM5 Six-In-One Multifunction CM5 Audio Base Adapter

Note

The #35D StationPi CM5 pre-production samples are currently being offered at a price below the cost. We have very limited stock available and just hope this allows customers to experience this new product even before its formal release.

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
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 independent and isolated GPIO connector for pure audio HATs (Optional, need to use U.FL and other cables)

J15: USB-C 5V power input

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)
