Pin Configuration

Stontronics T7725DV Power Supply For Raspberry Pi 4 Model B Pinout Guide
The Stontronics T7725DV Power Supply is a high-quality power supply specifically designed for the Raspberry Pi 4 Model B. This guide provides a detailed explanation of each pin on the power supply module, including their functions and connection guidelines.
Pinout Structure:
The T7725DV Power Supply has a total of 6 pins, arranged in a single row on the module. The pins are labeled as follows:
Pin 1: GND (Ground)
Function: Provides a common ground connection for the power supply and Raspberry Pi.
Connection: Connect to the GND pin on the Raspberry Pi 4 Model B.
Pin 2: VIN (Input Voltage)
Function: Accepts the input voltage from an external power source (e.g., wall adapter, battery).
Connection: Connect to a suitable external power source (e.g., 5V, 3A wall adapter).
Pin 3: VOUT (Output Voltage)
Function: Provides a regulated 5V output voltage to the Raspberry Pi.
Connection: Connect to the 5V pin on the Raspberry Pi 4 Model B.
Pin 4: EN (Enable)
Function: Enables or disables the power supply output.
Connection: Typically connected to a digital output on the Raspberry Pi (e.g., GPIO pin) to control the power supply. When the EN pin is high (logical 1), the power supply is enabled. When the EN pin is low (logical 0), the power supply is disabled.
Pin 5: PGOOD (Power Good)
Function: Indicates whether the power supply output is stable and within the acceptable voltage range.
Connection: Can be connected to a digital input on the Raspberry Pi (e.g., GPIO pin) to monitor the power supply status. When the PGOOD pin is high (logical 1), the power supply output is stable. When the PGOOD pin is low (logical 0), the power supply output is not stable.
Pin 6: FAULT (Fault Indication)
Function: Indicates if the power supply has detected a fault condition (e.g., overvoltage, undervoltage, overheating).
Connection: Can be connected to a digital input on the Raspberry Pi (e.g., GPIO pin) to monitor the fault status. When the FAULT pin is high (logical 1), a fault condition has been detected. When the FAULT pin is low (logical 0), no fault condition is present.
Connection Guidelines:
1. Ensure the power supply module is properly aligned with the Raspberry Pi 4 Model B before making connections.
2. Use suitable jumper wires or a breadboard to connect the pins between the power supply module and the Raspberry Pi.
3. Verify the input voltage and current rating of the external power source matches the requirements of the Raspberry Pi 4 Model B.
4. Implement proper electrical isolation and safety precautions when working with electrical components.
By following this pinout guide and connection guidelines, you can successfully integrate the Stontronics T7725DV Power Supply with your Raspberry Pi 4 Model B projects.
