This device controls low-side power switches for turning on and off solenoids, relays, and resistive loads.
- Connect a power supply to the power switch controller board.
- Connect devices to be switched to the shrouded header connectors on the board with either ribbon cables and IDC connectors or individual 2-pin connectors.
- Connect USB cable to from device to host machine and control over a serial port.
- This controller is made from a single 5x3 or 3x2 form factor modular device.
- This device consists of two pcbs, either the (modular_device_base_5x3) and the (power_switch_controller_5x3), or the (modular_device_base_3x2) and the (power_switch_controller_3x2).
- In addition to the two pcbs, there is one acrylic mounting plate (modular_device_enclosure 5x3 enclosure_bottom) or (modular_device_enclosure 3x2 enclosure_bottom).
- Send the zip files containing the gerbers for each of the two pcbs to your favorite pcb manufacturer for fabrication.
- Using the bill of materials and vendor parts lists order the parts necessary for construction for the two pcbs and the mounting plate.
- Assemble each of the pcbs using the assembly instructions provided for each.
- Use the dxf file for the enclosure_bottom to cut the mounting plate from the acrylic sheet using a laser cutter or send the dxf to a laser cutting service for fabrication.
