Step 1

Install 4x M3 heat-set inserts in the standoffs for the power board in the case bottom. Use a soldering iron on moderate temperature (~500F).

 

 

Next, install 4x M3 heat-set inserts in the case top. Use a soldering iron on moderate temperature (~500F).

 

 

Step 2

Use four M3x6mm bolts and install the power supply module in the case bottom.

Step 3

Install the screw terminals, DPS50XX display module and power switch in the front panel.

Step 4

Install the barrel jack socket in the rear panel and install the USB communications module using a pair of M3x6mm screws.

 

 

Step 5

Wire the power switch in line between the +ve power terminal of the barrel jack and the input to the DPS50XX power supply module.

 

 

Step 6

The 3.3V supply for the power switch LED can be tapped from an existing 3.3V regulator on the power supply module. Yellow wire = 3.3V, Black wire = GND.

 

 

Step 7

Complete the rest of the wiring for the screw terminals, LCD, Keypad and USB communications module.
