From the project

A power supply for a complete, Raspberry Pi based ADS-B Receiver Setup with independent power rails for the different components.

A power supply for a complete, Raspberry Pi based ADS-B Receiver Setup with independent power rails for the different components.

We sometimes face the problem that a normal Raspberry Pi power supply does not deliver enough power for the Raspi itself, the SDR Stick and possible other components like a display or even an SSD.

This board can be mounted underneath a Raspberry Pi and deliver stable 5.x V with up to 3 A to it.
