{"title":"Power Filter Board for Raspberry Pi 3B+/ 4B","handle":"power-filter-board-for-raspberry-pi-3b-4b","url":"/products/power-filter-board-for-raspberry-pi-3b-4b","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.\n\nThe 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.\n\nKey Features\n\n\nHybrid Capacitor Filtering – Solid, ceramic, and tantalum capacitors in parallel for full-spectrum noise reduction\n\n5,526 µF Total Capacitance – Substantial onboard filtering capacity\n\nGPIO Direct Connection – Plugs straight onto the Raspberry Pi header\n\nDC Power Input – 5V/3A input powers the Pi and connected modules\n\nBoard Protection – Helps protect your Raspberry Pi from power supply noise\n\n\nSpecifications\n\n\nCompatible Models – Raspberry Pi 3B+ / 4B\n\nOnboard Capacitance – 5,526 µF\n\nCapacitor Configuration – Parallel\n\nPower Input – 5V / 3A\n\nDimensions – 56 × 65 mm (2.20\" × 2.56\")\n\n\nIdeal For\n\nRaspberry Pi audio and Hi-Fi projects\nDAC and audio decoder setups\nAny Pi project requiring clean, stable power\n\n\nPackage Contents\n\n1× Raspberry Pi Power Filter Board\n4× Copper standoff, screw, and nut sets\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2522,"title":"Default Title","sku":"DF-DFR0940","price":34.7,"on_sale":false,"in_stock":true,"available_quantity":8,"option1":"Default Title"}]}
