What customers say
Users consistently praise the OB2-LF breakout board for its exceptional build quality and reliability. The robust FR4 material and superior plating significantly improve solderability, making the transition from surface mount devices to through hole remarkably smooth. Clear, accurate silkscreen labeling minimizes placement errors, speeding up development. Customers value the precise footprint dimensions that guarantee a perfect fit for integrated circuits. While priced slightly higher than generic options, the consensus is that the superior durability and time saved during prototyping fully justify the investment. This dependable tool is viewed as essential for serious electronic work, leading to strong recommendations and repeat business.
Know before you buy
The OB2-LF arrives as a ready-to-use assembly. The 5x8 solderless breadboard is pre-mounted to the FR4 PCB base, so you can begin prototyping immediately.
Mounting the breadboard to an FR4 PCB provides a rigid, durable foundation for your circuits. This setup is much more stable than using a standalone breadboard, especially when you are moving projects around your workspace.
Yes, the board includes mounting holes and the necessary 3mm hardware. This makes it easy to secure the unit to a project box or a custom chassis for a more permanent build.
The FR4 base measures 3.47 inches by 3.40 inches with a thickness of 0.062 inches. Its compact footprint is designed to save space on your workbench while providing enough room for standard prototyping tasks.
While the breadboard is pre-mounted for convenience, it is designed for standard prototyping use. If the contacts eventually wear out, you can remove the module and replace it with a standard adhesive-backed breadboard of the same size.
