⚡ Key Features

  • 12V to 5V Conversion — accepts 8–22V DC input and outputs a stable, regulated 5V DC
  • 15W / 3A Maximum Output — enough to power an ESP32 + a WS2812B LED strip or USB camera simultaneously
  • High Efficiency (up to 96%) — switching buck converter generates very little heat compared to linear regulators
  • Screw Terminal Connections — secure, tool-friendly wire connections on both input and output; no soldering needed
  • Compact PCB Module — small form factor fits inside electrical boxes, behind switches, or inside project enclosures
  • Over-Current & Short-Circuit Protection — built-in protection circuitry prevents damage to your connected devices
  • Wide Input Range (8–22V DC) — works with 12V gate motor batteries, 12V solar systems, car electrical, bench supplies, and 12V adapters

🏠 Perfect For

🚪

Gate Motor Power Tap

Power a SONOFF SV, ESP32, or smart relay from your gate motor's 12V battery. The converter provides clean 5V for logic-level devices without draining the battery excessively.

💡

WS2812B LED Strips

Convert a single 12V supply to 5V for WS2812B addressable LED strips. Pair with a WLED controller for smart RGB lighting powered from a 12V rail.

📷

CCTV / Camera Power

Power 5V USB cameras or Raspberry Pi boards from an existing 12V CCTV power rail. Eliminates the need for separate USB adapters at each camera location.

🏗️

DIY & Maker Projects

Arduino, ESP8266, ESP32, Raspberry Pi, sensors — anything that runs on 5V but needs to share a 12V power system. Ideal for home automation projects.

💡 Gate Automation Tip: Powering a eWeLink SV Inching WiFi Switch from your gate motor? The SV accepts 5–24V, but if your motor only has 12V and you need a clean 5V rail for other devices too, this converter gives you a reliable 5V tap from the gate battery.

❓ Frequently Asked Questions

Can I use this to power a Raspberry Pi?
Yes. The module outputs 5V at up to 3A — enough for a Raspberry Pi 3/4. Connect the 5V output to the Pi's 5V GPIO pins (pins 2 & 4 for +5V, pin 6 for GND). Note: this bypasses the Pi's USB-C power protection, so ensure your wiring is correct.
Does it work with a car 12V system?
Yes. Car electrical systems typically run 12–14.4V, well within the 8–22V input range. The converter will provide a stable 5V output even as your car battery voltage fluctuates.
Can I power WS2812B LED strips with this?
Yes, but check your current draw. At 3A max, you can safely power approximately 50 WS2812B LEDs at full white brightness (60mA each). For longer strips, you'll need a higher-rated 5V power supply.
What's the difference between this and a linear regulator?
A linear regulator (like a 7805) wastes the voltage difference as heat — converting 12V to 5V at 1A would burn 7W as heat. This switching buck converter is up to 96% efficient, producing very little heat and wasting almost no energy. Always use a buck converter for voltage differences greater than 2V.
Can I connect it to a 24V supply?
No. The maximum input is 22V DC. A 24V supply exceeds this and may damage the converter. For 24V input, look for a converter rated for 24V-to-5V.
