PD Trigger with voltmeter

I often test various DIY projects with different voltages, and I found a simple Power Delivery (PD) Trigger on AliExpress. If you have a power bank or a charger that supports Power Delivery with variable output, this trigger allows you to easily switch between 5V, 9V, 12V, 15V, and 20V.The addition of a small voltmeter makes things much easier and acts as a 'double-check' to ensure the correct voltage is set via the DIP switches.Switch positions are engraved on the bottom:1 — On (Up toggle)0 — Off (Down toggle)Assembly requirements: To build this, you will need a small voltmeter (I used the 2381BS model) and a PD trigger. Simply solder the voltmeter wires to the trigger's output. The top cover is secured with four M3 bolts.
