The MAX5969A receives power from the power-sourcing equipment (PSE) and provides 48V (nominal) of DC power to the MAX16832 LED driver and the MAX15062 DC-DC converter. The DC-DC converter powers the 8-bit microcontroller and the Bluetooth module. The microcontroller takes user input through the Bluetooth module and converts it to a PWM-dimming signal and feeds it to the LED driver.
The board accommodates footprints for an HM-12 BT module, a BL-600 BT module, and an ESP8266 Wi-Fi module. HM-12 control software for both Android and iOS is available. Search for “PoE LED” in the appropriate app store.
