JOY-IT B-POW Raspberry Pi rozširujúca doska napájania, 6-24V DC vstup, 5V 2,5A výstup

Deliver a stable 5V/2.5A to your Raspberry Pi from a wide 6–24V DC source with the JOY-IT B-POW power expansion board. The integrated DC/DC step-down converter accepts either a screw terminal or a 5.5×2.1mm barrel jack, making it easy to power your Pi from industrial supplies, battery packs, or existing power rails.

Overview

The B-POW is a stacking board that plugs directly onto the Raspberry Pi's 40-pin GPIO header, providing a regulated 5V supply to the Pi and connected peripherals. It is compatible with Raspberry Pi A+, B+, 2B, 3B, 3B+, and 4B. The board includes reverse polarity and overcurrent protection, plus a power LED for status indication.

What stands out

• Wide 6–24V input range via screw terminal or DC barrel jack
• High-efficiency DC/DC step-down conversion to 5V
• Up to 2.5A output current for demanding projects
• Reverse polarity and overcurrent protection
• Stacking design preserves GPIO access for other HATs
