STEVAL-LLL010V1 Data brief Evaluation kit for LED8102S 8-channel LED driver with direct switch control Features Double-sided LED board providing choice of white LED or RGB LED operation Full LED color temperature control thanks to 8-channel LED8102S LED driver Direct push button ON/OFF and dimming control STM32 MCU with firmware including demonstrative LED sequences Dedicated PWM signal for brightness and dimming management CE Certified RoHS and China RoHS compliant WEEE compliant (2012/19/UE RAEE II) Description The STEVAL-LLL010V1 kit consists of a two-sided LED panel board and separate control board with MCU and several user interface buttons. Each side of the LED board has an embedded LED8102S 8-channel LED driver IC and corresponding array of four independent white LEDS on one side, and a pair of three RGB LEDs in series on the other side. The control board mounts several switches for manual control of LED brightness and color on the white LEDs and RGB LEDs, respectively. An STM32F042 microcontroller is included to run LED control demonstration firmware to help users further evaluate the functionality of the featured LED8102S LED driver and develop custom applications. The entire kit is powered through a USB mini connector on the control board.

You can load custom application firmware onto the MCU through the J2 SWD connector, using an appropriate programming/ debugging device such as ST-Link. Figure 1. Control board top and bottom The control board has a mini USB connector to power itself and the connected LED board. Once both boards are connected and powered, the user interface buttons on the control board allow immediate manipulation of the LEDs in manual mode, or activation of the various automatic sequences available in the firmware. Figure 2. Control board switches PWR : toggles LED on/off with a gradual effect SEL : cycles through individual and global selection of available LEDs or LED strings UP/DOWN : press and hold to increase and decrease selected LED brightness DEMO : cycles through demonstration sequences available in the firmware UP SEL DEMO PWR DOWN The LED board in the kit has two separate control board connectors that allow you to control the four white LEDs on one side of the board, or the two rows of RGB LEDs on the other side of the board by orienting and connecting the board appropriately.
