12V DC Power Distribution Module

A compact and practical 12V DC power distribution board, ideal for ham radio, RF, and DIY electronics projects where multiple modules require a clean and organized power solution.

Key Features:
Built-in ON/OFF Switch for total system control
Power Relay & Fuse Protection with optional jumper bypass in case of relay or fuse failure
Reverse Polarity Protection – avoids damage from incorrect connections
8 + 8 Terminal Blocks for distributing power easily to multiple modules
Fully Assembled & Tested (DIY Kit version also available)
Compact Size: 6.5 x 5 cm (approx. 2.5″ x 2″)

Smart Power Management for Complex Projects
Originally designed by Christophe F1JKY for his 10 GHz transverter system, this board was developed to power multiple modules like RX/TX converters, power amps, and drivers – all from a single, clean 12V DC source.
Instead of bundling cables together, each module connects independently via terminal blocks for easy installation, removal, or field maintenance.

Built-In Protections for Field Use:
LED Power Indicator
Failsafe Design: If reverse polarity is detected, the diode D2 blocks activation, protecting your devices. The LED stays off, and only the fuse may blow.
Bypass Jumpers: Keep your system operational even if a relay or fuse fails during a critical operation or portable DX activation.

DIY-Friendly or Pre-Built:
Offered as either a solder-it-yourself kit or a ready-to-use, built & tested module
No SMD parts – easy to assemble with basic tools
Clear PCB markings on both sides for hassle-free assembly
