STEVAL-LLL011V1 Hardware Description

•The STEVAL-LLL011V1 contains 4 LED1202 ICs and 16

RGB LEDs. It can work in standalone mode or together with

the STSW-LED1202GUI PC SW by the onboard USB

connector. Two user buttons allow to interact with the board

by implementing user scripts. Additionally, an external Li-

ION battery can be connected to the board (see the slide 4).
