Features: 1.6 x SuperCap: This power filter board possesses 2CH common mode rejection, 6 x SuperCap, 6 x 47uf tantalum polymer capacitance with Low ESR connected in parallel, 3 x micro capacitance filter, with infrared receiver remote control. 2.2CH CMR: This DAC audio decoder board has 2CH common mode rejection filter circuit that can effectively suppress the power ripple of the power adapter. 3.3 x Micro Capacitance: This HIFI extension module adopts 3 x micro capacitance to filter spike ripple. And it supports Type C and DC2.1 input 5V. 4.Convenient Extension: This HIFI power filter board is designed for RasPi, suitable for moode, for volumio, for picoreplayer, for runeaudio. 5.6F=6000000F: This super capacitor filter board has 6F=6000000F power filter capacitor capacity. The input power supply is filtered by two sets of CMR filter circuit, and the secondary power supply is filtered by six channels of modified supercapacitor EDLC, and then filtered by six low ESR tantalum polymer capacitors. Finally, three sets of micro capacitors are sent to complete the end purification. specification:Item Type: Power Filter Board Material: Printed Circuit Board Power: 5V3A Application: Suitable for Moode, for Volumio, for Picoreplayer, for Runeaudio.
