STMicroelectronics STEVAL-ILL035V1 Demonstration Board

STMicroelectronics STEVAL-ILL035V1 Demonstration Board is designed to provide an application example of a compact LED backlight driver using the LED7708 device. The board is equipped with a 16-channel LED driver with an integrated boost controller (the LED7708), power section components, and an STM32 microcontroller to easily control all the features via a USB connection. The board has been designed as a demonstration of a solution for medium/large LCD panel backlight drivers, but it is suitable for any application involving several LEDs assembled in strings (e.g., advertisement panels, signs, gaming, etc.).
