Usage Instructions

• 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.

Build Instructions

• 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.

Supplemental Documentation

Assembly Instructions

• Solder header pins into the driver board, making note of TOP label. Insert header pins on bottom of board so that the long unsoldered header pins point down when the TOP label faces up.
• Solder surface mount and through hole components onto the pcb.
