STEVAL-LLL006V1 Smart LED driver using 6LoWPAN Mesh network for outdoor street lighting

The STEVAL-LLL006V1 board is designed to help you evaluate high power LED lighting solutions with comprehensive power management and wireless connectivity.

The board integrates an intelligent power conversion stage thanks to the HVLED001A LED lighting controller with various operating modes, sensing and protection mechanisms, and highly efficient switching based on the STP21N90K5 Power MOSFET. The board is able to convert a wide 90 - 300 VAC input voltage range into a 60 - 110 VDC output in constant current mode, with high power factor and low THD.

The on-board STM32L071KZ microcontroller is able to receive remote on, off and dimming commands via the embedded SPSGRFC sub-1 GHz transceiver module.

A data concentrator unit (DCU) and mobile Android application have been developed to help you explore the functionality of the evaluation board. The DCU consists of a NUCLEO-F401RE development platform, plus the X-NUCLEO-IDS01A4 for sub 1-GHz communication with the LED driver board and a X-NUCLEO-IDB05A2 board for Bluetooth communication with the mobile device.

The ST 6LoWPAN Smart Streetlight mobile application (available on Google Play store) collects lighting nodes represented by the microcontroller and RF module on the evaluation board in a 6LoWPAN mesh network.
