Purpose of the invented circuit is to reach requirement of using few or no conducting wire, and to include components required as far as possible. Printed connection wires (fig. 1-3) build paths between each loop (fig. 1-1) and adjacent loops (fig. 1-2) on vertical and horizontal coordinate. Based on need, selected connection wires are removed or reserved in use. Under precondition of low cost, comparing general multipurpose circuit board, the invented board raises availability and easy to use, providing solutions for all components.
