Type-C PD/QC/AFC Fast Charge Decoy Trigger Module – 5V/9V/12V/15V/20V Fixed Output
[Step UP Buck Converter] Type-C PD/QC/AFC Fast Charge Decoy Trigger Module – 5V/9V/12V/15V/20V Fixed Output The Type-C PD/QC/AFC Fast Charge Decoy Trigger Module is a compact USB Type-C power negotiation module designed to request a selected voltage from compatible USB Type-C fast chargers and power banks. It supports QC 2.0/3.0, AFC, PD 2.0 and PD 3.0 protocols, allowing compatible USB-C power sources to provide higher voltage outputs such as 5V, 9V, 12V, 15V or 20V. This module is useful for DIY electronics projects where a USB Type-C PD/QC charger needs to be used as a DC power source for equipment that does not have native USB-C fast-charging support. ⭐ Key Features USB Type-C fast-charge decoy/trigger module Supports PD 2.0 / PD 3.0 Supports QC 2.0 / QC 3.0 Supports Samsung AFC Fixed selectable voltage output Supports 5V / 9V / 12V / 15V / 20V output options Negotiates the required voltage from a compatible charger Suitable for USB-C power banks and PD adapters LED indicators for operating/status indication Compact and lightweight PCB design Useful for DIY power supply and electronics projects Plug-and-play operation with compatible USB-C power sources 📋 Technical Specifications Product Type: USB Type-C Fast Charge Trigger / Decoy Module Input Connector: USB Type-C Input Source: USB-C PD/QC/AFC compatible charger or power bank Supported Protocols: PD2.0, PD3.0, QC2.0, QC3.0, AFC Output Voltage: 5V / 9V / 12V / 15V / 20V Output Type: DC Voltage Selection: Fixed/selectable depending on module version Indicator: LED status indicators Application: DC power conversion and fast-charge voltage triggering 🔧 Applications Converting USB-C PD chargers into DC power supplies Powering DIY electronics projects Arduino and microcontroller projects LED applications Portable electronic equipment DIY laboratory power supplies DC motors and other suitable loads Router/modem power applications where the required voltage matches Powering electronics from USB-C PD power banks Replacing conventional DC adapters with USB-C PD sources 🛠️ How It Works The module does not boost the USB voltage itself. Instead, it communicates with a compatible USB-C power source and sends the required PD/QC/AFC negotiation request. For example, when connected to a compatible PD charger, the module can request: 5V → 9V → 12V → 15V → 20V The charger then provides the negotiated voltage at the module's DC output. ⚠️ Important Notes The connected USB-C charger or power bank must support the required fast-charging protocol and voltage. A standard 5V-only USB charger cannot normally provide 9V/12V/15V/20V through this module. Always verify the selected output voltage with a multimeter before connecting your device. Do not connect a device that requires a lower voltage than the selected output. The module is a trigger/decoy board, not a standalone DC-DC boost converter. Maximum available output power/current depends on the connected USB-C charger/power bank and the module's specifications. Do not short the output terminals. 20V output can damage 5V/9V/12V-only electronics if the wrong voltage is selected. Exact selectable voltages and current capability can vary between board versions. 📦 Package Includes 1 × Type-C PD/QC/AFC Fast Charge Decoy Trigger Module

5 Pin Mini SPDT Relay 12V 10A 250V PCB Mount Electromagnetic Relay
[Relay Module, Relays] 12V PCB Mount Sugar Cube SPDT Relay – 5 Pin 10A The 12V PCB Mount Sugar Cube SPDT Relay is a compact Single Pole Double Throw (SPDT) electromagnetic relay designed for switching AC and DC electrical loads using a microcontroller, sensor, automation circuit, or other low-power control system. Its compact PCB-mount design makes it suitable for DIY electronics, home automation, security systems, switching circuits, motor control, lighting control, and embedded applications. The relay features a 12V DC coil and a 5-pin SPDT configuration consisting of two coil terminals, COM (Common), NO (Normally Open), and NC (Normally Closed) contacts. When the coil is energized, the internal contact switches between the NC and NO terminals. With contact ratings of up to 10A at 250V AC, 10A at 125V AC, 12A at 120V DC, and 10A at 28V DC, this relay is suitable for a wide range of electrical switching applications. ⭐ Key Features SPDT (Single Pole Double Throw) relay 12V DC coil Compact Sugar Cube design 5-pin configuration PCB mounting type 10A @ 250V AC contact rating 10A @ 125V AC contact rating 12A @ 120V DC contact rating 10A @ 28V DC contact rating Coil resistance: approximately 270Ω Approximately 45mA nominal coil current 50/60Hz frequency specification Fast switching response Suitable for microcontroller and sensor-controlled switching Ideal for automation and control applications 📋 Technical Specifications Product Type: PCB Mount Relay Relay Type: SPDT (Single Pole Double Throw) Contact Configuration: 1 Form C Number of Pins: 5 Coil Voltage: 12V DC Trigger Voltage: 12V DC Coil Resistance: 270Ω Nominal Coil Current: Approximately 45mA Frequency: 50/60Hz Maximum AC Load: 10A @ 250V AC Maximum AC Load: 10A @ 125V AC Maximum DC Load: 12A @ 120V DC Maximum DC Load: 10A @ 28V DC Operating Time: 10ms Release Time: 5ms Mounting Type: PCB Mount Contact Terminals: COM / NO / NC Coil Terminals: Coil End 1 / Coil End 2 🔌 Pin Configuration Coil End 1: One terminal of the 12V DC relay coil Coil End 2: Other terminal of the 12V DC relay coil COM: Common switching contact NO: Normally Open contact NC: Normally Closed contact When the relay coil is not energized, COM is connected to NC. When the 12V DC coil is energized, COM switches from NC to NO. 🛠️ How It Works The relay uses an electromagnetic coil to mechanically switch an electrical circuit. Applying 12V DC to the coil energizes the relay and changes the contact position. A load connected between COM and NC remains connected when the relay is inactive. A load connected between COM and NO remains disconnected until the relay coil is energized. This allows a low-power control circuit such as an Arduino, microcontroller, sensor, timer, or automation controller to control a higher-current AC or DC load. 🔧 Applications Arduino Projects Microcontroller Projects Sensor-Controlled Switching Home Automation Security Systems Lighting Control Fan Control Motor Control Pump Control Power Supply Switching Industrial Control Systems Embedded Electronics DIY Electronics Projects 📦 Package Includes 1 × 12V PCB Mount Sugar Cube SPDT Relay – 5 Pin 10A ⚠️ Precautions Use a suitable 12V DC supply for the relay coil. Do not exceed the specified contact voltage and current ratings. Check the COM, NO, NC, and coil terminals before wiring. Use suitable flyback protection when driving the relay coil from sensitive electronic circuits. Use appropriate suppression/protection components for inductive loads such as motors, solenoids, and coils. Provide sufficient PCB insulation and clearance when switching mains voltage. Disconnect power before changing or modifying wiring. Do not touch exposed mains-voltage terminals during operation.
