The USB-C PD Trigger Decoy Module with Selectable Voltage Output is a tiny board that connects to any USB-C fast-charge adapter and negotiates a fixed output voltage from the charger — so the same USB-C charger that normally charges a phone can be made to output 9V, 12V, 15V, or 20V DC as a power supply for a project. This pd trigger module works because USB-C PD (Power Delivery) chargers do not output their full voltage automatically — they start at 5V and wait for a connected device to request a higher voltage through a negotiation process. This module acts as that device, requesting exactly the voltage set on its DIP switches, and the charger then delivers that fixed voltage on the output terminals.
The trigger decoy board module’s DIP switches make voltage selection straightforward — flip the switches to the combination matching the required voltage (5V, 9V, 12V, 15V, or 20V), connect to a compatible USB-C charger, and the output terminals immediately provide that stable DC voltage at up to 3A depending on the charger’s rated output. The pd decoy module supports PD2.0, PD3.0, QC2.0, QC3.0, and AFC protocols, covering virtually all major fast-charge USB-C adapters.
The usb c pd trigger module’s onboard protection covers overvoltage, overcurrent, and thermal conditions, and its compact 31×20mm footprint fits into project enclosures, custom power supply builds, and bench supply setups with minimal space. Available from StemVolt, delivering genuine electronics modules.
