Product overview

Description

The STEVAL–POEL45W1 Power over Ethernet (PoE) powered LED driver reference design delivers a power output of 45 W and dims LEDs down to 1% of the maximum brightness without any flicker. The solution supports remote dimming control via Bluetooth with the PoE_Lighting Android application (available on Google Play).

You can use this reference design to develop complete indoor network-powered lighting solutions with IP-based Powered Devices (PDs), without additional AC power infrastructure, and extend the functionality to include remote data management via existing LAN networks.

The reference design features a highly integrated PM8805 IEEE802.3bt-compliant Powered Device (PD) PoE interface, a high efficiency LED6000 LED driver able to source up to 3 ADC current, and a certified SPBTLE-1S Bluetooth Low Energy module, compliant with BT specifications v4.2 and BQE qualified.

For new designs, the BLUENRG-M2SA module for Bluetooth® low energy v5.2 is recommended.

SPBTLE-1S and BLUENRG-M2SA are pin to pin compatible.

The STSW-POEL45FW board firmware is programmed via the STSW-BNRG1STLINK utility.
