Power Filter Board for Raspberry Pi 3B+/ 4B

The Power Filter Board for Raspberry Pi 3B+/ 4B is a dedicated power conditioning add-on designed to eliminate electrical interference across low, mid, and high frequencies. Ideal for audio enthusiasts, makers, and students, it provides clean, stable power to protect your single-board computer and optimise audio output.

Parallel hybrid filtering design

The board integrates an array of solid, ceramic, and tantalum capacitors connected in parallel to achieve a total capacitance of 5526uF. This hybrid setup filters low, medium, and high-frequency power supply noise to deliver exceptionally smooth power.

Purer audio and DAC performance

By eliminating ripple and interference from the power source, the filter delivers purer sound quality when combined with Raspberry Pi DAC audio decoder boards. It provides the clean signal foundation needed to turn your board into a high-fidelity stereo streamer.

Controller protection and power delivery

Accepting a 5V/3A DC power input, the board powers the Raspberry Pi and attached accessories while shielding the main processor from power instability. This consistent supply helps prevent damage and extends the operational life of your hardware.

Direct GPIO connection and mounting

With a compact footprint of 56 x 65 mm, the module plugs directly into the GPIO header on the Raspberry Pi 3B+ or 4B. Four sets of copper pillars, screws, and nuts are included for secure physical installation.
