TypeC QC AFC PD2.0/PD3.0 to DC FastCharge Trigger / Polling Detector Board Module Key benefits Enables USBC PD and QC/AFC chargers to supply fixed DC voltages required by devices that expect a DC input. Solves compatibility gaps between modern USBC fast chargers and older DCpowered equipment. Lets you force or emulate fastcharge negotiations (trigger/polling detector) so the source presents the correct voltage profile for your device. Easy voltage selection via DIP switches using the reference table printed on the back of the board — no soldering or firmware required. What it does Acts as a TypeC to DC converter and PD trigger module that negotiates with USBC power sources and outputs a selectable DC voltage. Supports fast charging protocols: PD2.0, PD3.0, QC2.0, QC3.0, and AFC. Voltage options: 5V, 9V, 12V, 15V, 20V (fixed steps only; variable or arbitrary voltage steps are not supported). Key features and compatibility Interface: USB TypeC input to DC output (board/module form). Fastcharge protocol compatibility: PD2.0, PD3.0, QC2.0, QC3.0, AFC — works with chargers and power banks that implement these protocols. Voltage selection: Set the desired output by toggling the DIP switches according to the table printed on the back of the board. Output voltages supported: 5V, 9V, 12V, 15V, 20V. Note: voltage step control (continuous or microstep adjustment) is not provided. Function: Triggering/polling detector for USBPD notebook power supplies and other DCpowered devices. Performance notes Provides reliable negotiation with supported PD/QC/AFC sources to obtain one of the predefined DC voltages. Voltage mapping and DIP switch positions are printed on the module for straightforward configuration. Intended to be used as a control/conversion module; ensure current and connector compatibility with your target device. Typical use scenarios Adapting a modern USBC PD or QC fast charger to power a notebook or other device that accepts a DC barrel input at 9V, 12V, 15V, or 20V. Testing or diagnosing power negotiation on USBPD chargers and laptop power supplies by forcing specific PD/QC/AFC voltages during development or . Converting USBC power banks or singleoutput PD chargers to feed lab equipment, routers, or other DCpowered devices that require one of the supported fixed voltages. Practical considerations Configure voltage using the DIP switches and the table printed on the back of the board before connecting the load. Confirm the target device's required voltage and current capability of your USBC power source to avoid underpowering or overvoltage. This module is a control/polling board; use appropriate cables and connectors for the DC output and ensure proper current rating for your application.
