StoryWe have developed PPSTrigger awhile back as a way to request Programable Power Supply (PPS) mode from modern USB-C charger. This mode allow you to request fine voltage directly from the charger the usual range 3.3V to 20V. All you need to do is to turn the trim pot in the PCB to get your desire voltage.
PPSTrigger V1.1 comes with M2 heat insert, bolt and screw. There is no M2.5 heat insert included.
Step 1: Solder the RED to + and BLACK to -, Like so:
Step 2: Add your M2.5 heat insert. For PLA, you can use solder iron set at 200C. M2.5 heat insert and bolt will need to be purchased separately.
Step 3: Screw in your PPSTrigger board with M2 screw (6mm)
Step 4: Screw in your voltmeter
Charger selectionWe have a list of tested charger but there are just many many charger out there can can do the same thing. You just need to watch out for the term "PPS" mention in the capability.
- UGREEN 100W - PPS 3.3 - 21.0 @ 3A
- UGREEN 140W - PPS 3.3 - 21.0 @ 5A
- AOHI Magcube 140W - PPS 3.3 - 21.0 @ 5A
- GKUTW HX65P3 65W - PPS 3.3 - 21 @ 3A
- Anker 737 (GaN Prime 120W) - PPS 3.3 - 11.0 @ 3A
- Anker 737 Power Bank - PPS 3.3 - 21.0 @ 5A
- Anker PowerHouse 521 - PPS 3.3 - 11.0 @ 3A
ResultConnect anything to your screw terminals and enjoy high amperage supply! Depend on charger and cable, you can get up to 5A at any voltage. Example is the UGREEN 140W pair with a 100W cable.
NoteThe trim pot does not have an infinite life time so limit the amount of time you adjust it. If you want to make it more robust, we suggest you remove the trimpot and replace with a 10K potentiometer.
