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 […]

Renesas RRH47000-EVK board integrates RRH47000 CO2 sensor with ±75 ppm accuracy, relative humidity and temperature sensors

Renesas has recently released the RRH47000-EVK evaluation board based on the RRH47000 CO2 sensor using non-dispersive infrared (NDIR) technology to measure CO2 levels accurately (±75 ppm typical) within the 0-5000 ppm range. The sensor also includes built-in sensors for relative humidity and temperature, operates at low power, and supports either UART or I2C interface to the host. These features make this device useful for applications like HVAC systems, industrial automation, building control, air quality monitors, home appliances, IoT devices, and agriculture. Previously we have written about the Sensirion SCD40 CO2 sensor which also uses NDIR to measure CO2 levels very accurately, while the Infineon PASCO2V15 CO2 sensor relies on photoacoustic spectroscopy (PAS) to detect CO2 levels. The Sensirion sensor can also measure humidity and temperature, but the Infineon sensor is designed to measure CO2 only. Renesas RRH47000 specifications: CO2 sensor Measurement range – 0 ppm to 5000 ppm Accuracy – […]
