Introduction
ShieldPi Pro 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 (MkIII)
- An IR-remote control Receiver (MkIII)
- 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.
Highlighted Features and Specifications
- Zero current single-point grounding shield plate to eliminate EMI noise of the Raspberry Pi
- Ultra-low ESR wide bandwidth 5V power supply filtering networks cover the frequency range up to GHz
ESR: 2mΩ@200KHz, 0.3mΩ/@2Mhz, 1mΩ@20MHz, 4mΩ/@200MHz - Full 40 pins GPIO extender
- Full 40 pins GPIO multiplier (AUX GPIO)
- Has a Raspberry Pi GPIO power ON/OFF button and a connector to external power button
- Has an optional power on indication LED and a power on/off control signal output
- Can implement Raspberry Pi’s IR-remote control function when working with a MonitorPi
- Reduce both EMI noise and power supply noise
- Improve Raspberry Pi application’s performance to a higher level
- DIY friendly and plug and play
ShieldPi Pro MkII new features
- Full size shield HAT that can cover the whole Raspberry Pi PCB area
- Better EMI suspension performance will be expected
- High profile GPIO connector makes it possible to work with RPi that is equipped with a heatsink
- ON/OFF button moved to the front edge of PCB to make it easier to operate
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

Customer Reviews
It works very well and is certainly a clear improvement of the power supply of the raspberry PI as well as being an excellent shield for EMI. I am very satisfied
Alessandro Catalano
I thought I was going to have to throw my ucpi in the bin and spend double to get a purepi but getting this allowed me to have a clean 3.3v output for my fifopi ma 1.5 reclocker.. not only that but it helps in other ways. really happy with it!
Put the ShieldPi Pro between my 3 B+ and my PiAES2 hat and what an improvement. Well worth the few bucks for the bump in performance.
Does exactly what it says and showed up quickly thanks Ian!
