Home Assistant-compatible 5-24V LED strip controller ships with Sound Reactive WLED firmware

SMLIGHT A1-SLWF-03 is a Home Assistant-compatible addressable RGB LED strip controller based on an ESP32 WiFi and Bluetooth microcontroller that supports 5V to 24V LED strips. The unit is equipped with a built-in digital microphone used by the Sound Reactive WLED firmware to make the RGB LED strip follow the rhythm and tempo of the music, an IR receiver, and a sensor button. SMLIGHT A1-SLWF-03 specifications: SoC – ESP32 dual-core microcontroller with WiFi 4, Bluetooth 4.2/5.x, and 16Mbit flash 4-pole terminal block for RGB LED strips Supported strips – WS2812B, WS2811, WS2813, WS2815, APA102, LPD8806, WS2801, SK9822. Voltage Range – 5-24V DC Up to 2,000 LEDs are supported at 35 fps with two outputs or 3,000 LEDs at 25 fps with two outputs (about 33 to 50-meter LED strips with 60x LEDs per meter) Multiple A1-SPWF-03 controllers can be synced together for controlling even more LED strips. USB – 1x […]

5V wireless LED lights up thanks to magnetic resonance coupling technology

Wireless power, no matter how inefficient it may be, sounds good and even looks good with the “5V remote wireless power supply LED pack” we feature in this post. It also feels magical with the LEDs lighting up thanks to magnetic resonance coupling technology. The solution comes with a coil as a transmitter and each LED bead also includes a small coil as a receiver. When the two are coupled, energy can be transferred from the transmitter to the receiver through the air, paper, or plastic casing, and the LEDs will light up. The magnetic field intensity in this technology is said to be similar to that of the Earth’s magnetic field, and it will not be harmful to human health and other devices. Specifications: Transmitter Module Input Voltage – 5 V Power – 0.5W (10 LEDs) Transmitting Coil Outer Diameter – 70mm, inner diameter 65mm, thickness 0.5mm Transmitter Board […]
