Description

Technical Field

[0002] A breadboard is a tool designed specifically for solderless experiments with electronic circuits. It is made of thermosetting phenolic resin, with a metal strip embedded in the bottom and regular holes on the surface. When electronic components (such as resistors, capacitors, and integrated circuits) are inserted into the holes, the component leads are electrically connected through the metal strip, thus quickly building a temporary circuit.

[0003] Traditional breadboards rely on external jumpers for node connections during communication, which can easily lead to wire crossings, misconnections, and poor contact, thus affecting the reliability and anti-interference capabilities of the circuit connections. For example, poor contact between jumper plugs and sockets can occur due to oxidation or loosening, causing intermittent circuit failures. Furthermore, the complex wiring structure formed by numerous jumpers on the circuit board can easily introduce electromagnetic interference. These interference signals can affect the transmission and processing of weak signals in the circuit, leading to signal distortion, bit errors, and other problems. Therefore, we need to propose a programmable electronic circuit connection control device to solve the above-mentioned problems. This device should be able to replace physical jumpers through internal chip routing and dynamic control, forming a zero-crossing connection matrix and improving the reliability and anti-interference capabilities of the circuit connections.

Through the serial data bus, management chip U2 sends control commands to multi-channel crossbar switch chips. Data loading and addressing are completed synchronously using STB (strobe pulse) and DAT (data).
