Pin Configuration

Hi-Link 3.3V 1.5A Power Module Pinout Guide
The Hi-Link 3.3V 1.5A Power Module is a compact, high-efficiency DC-DC power module designed for a wide range of IoT applications. This documentation provides a detailed explanation of the module's pinouts, helping you connect and utilize the module effectively.
Pinout Structure:
The Hi-Link 3.3V 1.5A Power Module has a total of 4 pins, arranged in a single row. The pins are labeled as follows:
Pin 1: VIN (Input Voltage)
--------------------------------
Function: Input voltage pin for the power module
Voltage Range: 4V to 24V DC
Recommended Operating Voltage: 5V to 12V DC
Current Rating: Up to 1.5A
This pin is used to connect the input power source to the module. The input voltage range is from 4V to 24V DC, but it's recommended to operate within 5V to 12V DC for optimal performance.
Pin 2: GND (Ground)
-------------------------
Function: Ground pin for the power module
Purpose: Provides a common ground connection for the module
This pin is the ground connection for the power module and should be connected to the ground of your circuit or system.
Pin 3: VOUT (Output Voltage)
------------------------------
Function: Regulated output voltage pin
Output Voltage: 3.3V DC
Current Rating: Up to 1.5A
This pin provides a regulated 3.3V DC output, which can be used to power your IoT devices or circuits. The maximum current rating is 1.5A.
Pin 4: EN (Enable)
---------------------
Function: Enable pin for the power module
Logic Level: Active High (EN = High: Module Enabled, EN = Low: Module Disabled)
This pin is used to enable or disable the power module. When the EN pin is pulled high (connected to VIN or a logic high level), the module is enabled, and the output voltage is regulated to 3.3V DC. When the EN pin is pulled low (connected to GND or a logic low level), the module is disabled, and the output voltage is shut down.
Connection Guidelines:
1. Connect the input power source (4V to 24V DC) to Pin 1 (VIN).
2. Connect the ground of your circuit or system to Pin 2 (GND).
3. Connect the load or IoT device to Pin 3 (VOUT) to receive the regulated 3.3V DC output.
4. Connect the enable signal (logic high or low) to Pin 4 (EN) to control the power module's operation.
Remember to follow proper safety precautions and handling guidelines when working with electrical components. Ensure that your circuit or system is designed to operate within the recommended specifications of the Hi-Link 3.3V 1.5A Power Module.

Notes and Precautions

Make sure to connect the input voltage (VIN) within the recommended range of 4.5-12V to avoid damage to the module.
 The module has a built-in overcurrent protection (OCP) and short-circuit protection (SCP) to prevent damage from excessive current or short circuits.
 Ensure proper heat dissipation for the module, especially when operating at high loads.
 Always follow proper safety precautions when working with electronic components.
