Eurorack Power Bus Board

Eurorack Bus Board PCB

The Eurorack Bus Board PCB is a compact, chainable power distribution board designed for Eurorack modular synthesizer systems. This PCB-only version allows builders to distribute power and control signals efficiently while customizing component selection to suit their system requirements.

Key Features

• PCB-only Eurorack bus board
• Distributes +12V, -12V, +5V, GND, Gate, and CV
• 8 16 pin IDC connector power slots for Eurorack modules
• Optional decoupling capacitors for improved power stability
• Optional LED indicators with adjustable brightness
• Chainable design for expanding the number of power slots
• Compact footprint for flexible case layouts

Power Distribution & Expansion

This Eurorack bus board PCB provides reliable distribution of power and control signals to your modular system. The chainable design allows multiple boards to be connected together, making it easy to expand your system as it grows. Optional decoupling capacitors can be added to improve power stability, especially in larger or more demanding setups.
