The Device is a monolithic integrated high voltage,high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.
The mechanical endstop uses a lever switch to detect when it is activated. The switch is wired up so that when activated, it pulls the signal to LOW. There is also an LED on the board that will light up when the switch is activated.It uses a standard 4 pin .100″” pitch header and accepts a standard, old-style CD-ROM audio connector cable. Brand new and high quality. The endstop is a reliable endstop / switch solution for any type of 3D printers and other CNC and/ or 3D tools.
