ANAVI Miracle Emitter – A WiFi and BLE RGB LED controller compatible with Home Assistant, WLED firmware (Crowdfunding)

ANAVI Miracle Emitter is an open-source hardware ESP32-C3 WiFi and BLE controller designed to control 5V addressable RGB LED strips, which works with Home Assistant over MQTT and also supports the popular WLED firmware to easily control the LED strip through a web interface. It also features four I2C expansion headers for sensors and a small OLED display, a UART header, and a GPIO header. It’s an update to Leon ANAVI’s Miracle Controller introduced in 2019 with an ESP8266. A lot of things have changed since then, and it’s gotten easier than ever to control RGB LED strips using open-source software and firmware. ANAVI Miracle Emitter specifications: Wireless Module – Seeed Studio XIAO ESP32C3 Wireless MCU –  Espressif Systems ESP32-C3 single-core RISC-V microcontroller @ 160 MHz with 400KB SRAM, 384KB ROM, 4MB flash, Wi-Fi 4 & Bluetooth LE 5.0 connectivity Antenna – External u.FL antenna USB – USB Type-C port […]

ESP32-based YULC USB-C LED Controller features dual power inputs, supports WLED and ESPHome firmware

The YULC (Yes, a USB-C LED Controller) board is a compact, ESP32-S3-powered LED controller with USB-C and DC jack power inputs. It is a fully featured board that can easily replace a rat’s nest of wires and save space and time. This ESP32 LED controller features a built-in buck regulator that converts input power from the USB-C port or barrel jack to the voltage needed for the LED strips. The YULC provides two separate LED channels with a level shifter each to ensure clean and powerful data output, removing the need for a sacrificial pixel or external level shifter. Each channel also has a power MOSFET that can turn off the channels individually and dim simple LED strips via PWM. AAElectronics, the maker, has previously released an IR remote—the Home Assistant-compatible ESP 360 Remote—which we covered at the time. Similar products include the SMLIGHT A1-SLWF-03, DFRobot’s EDGE102-DMX512, and the PixelBlaze […]
