ShieldPi Pro MkIII is not only a powerful Raspberry Pi EMI shield HAT, but also:
- A high-performance power supply cleaner/filter
- Raspberry safe ON/OFF button
- A GPIO extender/multiplier
- An ultra-low noise 3.3V power supply
- An IR-remote control Receiver
- Power a RaspberryPi from GPIO
- Power ON/OFF indication and signal
ShieldPi Pro is suitable to all RespberryPi applications to reduce EMI noise and improve power supply performance. Improvement can be made right away by just installing it into GPIO connector of a RaspberryPi.
ShieldPi Pro MkIII new upgrades over MkII
- Built-in ultra-low noise 3.3V/500mA power supply, capable of powering FifoPi, DAC or other devices without using additional 3.3V power supply
- Optical receiver makes IR remote controller working for RaspberryPi
- 5V input/output connector can power a RaspberryPi directly from GPIO with bypassing the USB power input.
- Optimized PCB layout
Typical Applications
Upgrade the high performance Audiophonics I-Sabre ES9038Q2M DAC
Improve the TransportPi Digi/II network streamer transport
Upgrade a standard RaspberryPi DAC
Upgrade a basic RaspberryPi DAC or digi streamer transport
Run a FifoPiQ7or FifoPi MA directly without using an additional 3.3V power supply
Run a IanCanada ESS DAC directly without using an additional 3.3V power supply
ShieldPi Pro MkIII works with Raspberry Pi that is equipped with a heatsink

A serious issue with above stacking examples is the cooling of a PI, especially when using a PI5. The caps of your filter sit right in the oven.
PI5s are usually shown with active cooling, though passive also works quite well with proper ventilation space.
The last image image seems to show a use of a very flat heatsink. That’s new to me and nice to see, even though the ventilation area is not that great.
Could you please point out what heatsink you are using and what impact you see on the temperature side at PI5 default clock rate of 2.4.GHz. Thx.
hello,
I’d like to find out what you recommend for the bare minimum configuration to have a top quality dac with spdif digital input and RCA analog outputs. I don’t need a streamer or USB connection or balanced outputs. Can you give me a recommendation?
Thanks,
Herman
