STMicroelectronics STEVAL-LLL010V1 Evaluation Kit is comprised of a two-sided LED panel board and a separate control board with MCU and several user interface buttons.
On each side of the LED board, there is an embedded LED8102S 8-channel LED driver IC. On one side of the board is an array of four independent white LEDs, while on the other side is a pair of three RGB LEDs in series. The control board mounts several switches for manual control of LED brightness (white) and color (RGB).
An STM32F042 microcontroller is included to run LED control demonstration firmware. The firmware allows users to evaluate further the functionality of the featured LED8102S LED driver and develop custom applications. The entire STM STEVAL-LLL010V1 Evaluation Kit is powered through a USB mini connector on the control board.
