The pipe circuit

Water pipe circuit through. We package each electronic component in an independent module, and mark it with silkscreen and lamp on the module shell. Unified module interface, with the way of splicing blocks so that all kinds of electronic components can be arbitrarily combined. No more messy panel trouble, also avoid the difficulty and danger of soldering iron welding. Each module has built-in protection circuit, even if misspelled will not burn the device. Every time a module is connected, the circuit path on the module will become bright, so as to show the user in a clear and intuitive form
