High Density: 4X4 Series

COB modules are ready for plug and play with no soldering required. All Violumas COBs have built-in connectors for easy wiring and testing.

Protection from ESD

Every Violumas COB module includes TVS protection on the MCPCB to help control electrostatic discharge damage.

Easy Integration

COBs can be assembled in a modular fashion to allow for easy integration and testing without the need for a separate MCPCB.

Standard Heatsinks & Drivers

Violumas is able to provide suitable heatsinks & drivers for all standard COB modules so you can initiate immediate testing.
