STMicroelectronics STEVAL-LLL006V1 Smart LED Driver Board

STMicroelectronics STEVAL-LLL006V1 Smart LED Driver Board evaluates high-power LED solutions with comprehensive power management and wireless connectivity. This board integrates an intelligent power conversion stage based on the HVLED001A high-voltage LED driver. The STMicroelectronics STEVAL-LLL006V1 Smart LED Driver Board includes the STM32L071KZ microcontroller that can receive remote on, off, and dimming commands through the embedded SPSGRFC transceiver module. The functionality of this LED driver board can be evaluated through a Data Concentrator Unit (DCU) and mobile Android application. The mobile application collects lighting nodes represented by the microcontroller and RF module on the evaluation board in a 6LoWPAN mesh network.
