## Description

This power filter board for Raspberry Pi integrates solid capacitors, ceramic capacitors, and tantalum capacitors in a parallel hybrid filtering configuration. It filters low, mid, and high-frequency power noise from your supply, delivering cleaner power to the entire system — particularly beneficial for audio projects where sound quality matters. The board plugs directly onto the Raspberry Pi GPIO header and includes a DC power input to supply power to both the filter board and the Pi. When paired with a DAC audio decoder board, it helps turn your Raspberry Pi into a high-quality stereo system. It also provides effective power protection to help extend the service life of your Pi. Key Features Hybrid Capacitor Filtering – Solid, ceramic, and tantalum capacitors in parallel for full-spectrum noise reduction 5,526 µF Total Capacitance – Substantial onboard filtering capacity GPIO Direct Connection – Plugs straight onto the Raspberry Pi header DC Power Input – 5V/3A input powers the Pi and connected modules Board Protection – Helps protect your Raspberry Pi from power supply noise Specifications Compatible Models – Raspberry Pi 3B+ / 4B Onboard Capacitance – 5,526 µF Capacitor Configuration – Parallel Power Input – 5V / 3A Dimensions – 56 × 65 mm (2.20" × 2.56") Ideal For Raspberry Pi audio and Hi-Fi projects DAC and audio decoder setups Any Pi project requiring clean, stable power Package Contents 1× Raspberry Pi Power Filter Board 4× Copper standoff, screw, and nut sets
