In stock
The DC Power Shield V1.1.0 for WEMOS D1 Mini is an expansion board (shield) specifically designed to provide a convenient and regulated DC power supply to the popular WEMOS D1 Mini ESP8266 development board. It simplifies powering your D1 Mini projects, especially when you need a stable voltage source from various DC inputs.
Here’s a breakdown of its key features and characteristics:
Core Function:
- DC Power Input: Allows you to connect a DC power source (like a wall adapter, battery pack, etc.) to your WEMOS D1 Mini.
- Voltage Regulation: Contains an onboard voltage regulator to step down the input voltage to a stable 5V, which is the operating voltage for the WEMOS D1 Mini.
- Powering the D1 Mini: Provides a reliable 5V power supply to the D1 Mini through its header pins, eliminating the need to power it via the micro-USB port.
Key Features and Specifications (may vary slightly depending on the exact manufacturer and revision):
- Input Voltage Range: Typically supports a wider range of DC input voltages, often around 7V to 24V DC. This allows you to use various power adapters or batteries.
- Output Voltage: Regulated 5V DC.
- Output Current: The maximum output current depends on the voltage regulator used on the shield and the input voltage. It’s usually sufficient to power the D1 Mini and some small peripherals, often in the range of around 1A or slightly more. Always check the specific datasheet for the exact current rating.
- Power Input Connector: Usually features a DC barrel jack connector (e.g., 5.5mm x 2.1mm) for easy connection of standard DC power adapters. Some versions might also include screw terminals for more secure or custom wiring.
- Power Indicator LED: Typically includes an LED that lights up when the shield is receiving power.
- Pass-through Headers: Designed with female headers that allow you to stack other WEMOS D1 Mini compatible shields on top of it. This maintains the expandability of the D1 Mini.
- Compact Form Factor: Matches the small size of the WEMOS D1 Mini, ensuring a neat and integrated setup.
- Reverse Polarity Protection: Some versions might include a diode for reverse polarity protection on the input, preventing damage if the power supply is connected incorrectly. Check the specific documentation.
- On/Off Switch (Optional): Some variations of the DC Power Shield might include an on/off switch for convenient power control of the entire D1 Mini setup.
Benefits of Using the DC Power Shield V1.1.0:
- Convenient Powering: Simplifies powering your D1 Mini projects without relying solely on the micro-USB port, which can be less robust for permanent installations.
- Wider Input Voltage Range: Allows you to use a broader range of DC power sources.
- Stable 5V Supply: Provides a regulated and stable 5V, ensuring reliable operation of the D1 Mini and connected peripherals.
- Easy Integration: Plugs directly onto the WEMOS D1 Mini, making it easy to assemble.
- Stackable Design: Maintains compatibility with other D1 Mini shields.
- Suitable for Permanent Installations: Offers a more robust power connection compared to USB.
Typical Applications:
- IoT Projects: Powering sensors, actuators, and other peripherals connected to the D1 Mini.
- Home Automation: Providing reliable power for smart home devices.
- Robotics: Powering control boards and small motors.
- Data Logging: Ensuring continuous power for data acquisition systems.
- Standalone Projects: When the D1 Mini needs to operate independently of a computer’s USB port.
In summary, the DC Power Shield V1.1.0 for WEMOS D1 Mini is a valuable add-on that provides a dedicated and regulated DC power supply for your ESP8266 projects, offering convenience, stability, and flexibility in power source options. Always refer to the specific documentation or product page for the exact specifications and features of the particular shield you are using.
