High brightness RGB LED array with LED error detection based on the STP24DP05 and STM32

The STEVAL-ILL015V1 demonstration board provides a platform for the testing and evaluation of STMicroelectronics’ Power Logic LED driver STP24DP05.

The STP24DP05 device is a 24-bit constant current LED sink driver with output error detection, suitable for applications such as largearea displays and full-color board panels where improvement in RGB LED resolution and reduction of system cost are important.
