The 0.1 inch pitch XR0280/C prototyping board has numerous features not found in competing designs:

* Most cost effective size for manufacture.

* 3 rails for mixed voltage prototyping or optional debug lights.

* Thick traces on 2 sides to reduce unwanted inductance.

* Scalable, octagonal, twin nested serpentine power rail system to reduce unwanted EMF.

* Consistent row numbering on both sides. (Unlike some cheap breadboards.)

* Silkscreen on 2 sides for consistent alignment of 8 * 16 Pin DIP.

* Consistent corner mounting holes for 3mm thread hex bolt stacking.

* Boards can be daisychained or used in mesh configuration with minimum voltage drop.

* Suitable for complex designs. 10 prototype boards are sufficient to make TTL CPU.

Overall, XR0280/C is the best combination of cost, reliability, flexibility and scalability.

Design variants are available on request. This includes designs which are shorter, longer, wider, with more rails or 4-4-4 pattern more suitable for analog prototyping. Also available in any color with your choice of text!
