The BR1 and SB830 are both single-sided solderable PCBs designed to match the pattern of a standard 830 tie-point solderless breadboard. Both have the same 5-hole strip layout and 0.1” (2.54 mm) hold spacing as the BB830, so circuits transfer directly without recutting wires or repositioning components. They are similar PCBs and excellent choices for making permanent prototypes from full-size breadboards.

The BR1 is our original Solderable PC BreadBoard with a matching pattern to our BB830 Solderless BreadBoard. With input from customers, we developed the SB830.

The key differences are:

• Length: The SB830 is slightly longer than the BR1. The mounting holes are positioned further from the IC area, making it easier to secure the board in enclosures without screw heads interfering with components.
• Track width between holes: The SB830 uses narrower tracks between holes (40 mil vs. 85 mil on the BR1), making it easier to cut tracks cleanly and with less risk of leaving a copper sliver.
• Bonus pad pattern: On the SB830, the bonus pads at each end of the board use the same 2-hole strip pattern as the rest of the board. The BR1 uses a pad-per-hole pattern at the ends, which is less consistent with the rest of the layout.

Both boards have six power rails and the same rail spacing as the BB830, so power connections transfer directly. The BR1 is available for customers who know and rely on including it in their prototypes. The SB830 improves upon the BR1 and is easier to work with for most applications.
