The STEVAL-ILL035V2 product evaluation board is an extension (daughterboard) of the STEVAL-ILL035V1 (motherboard) based on the LED7708 LED driver. It allows implementation of a daisy-chained configuration for applications requiring more than 16 channels. The LED7708 is configured as slave on the STEVAL-ILL035V2, and as master on the STEVAL-ILL035V1.
The boost controller section is not used and the supply voltage for the LED strings is derived from the motherboard (STEVAL-ILL035V1, master) by extending the output voltage optimization through dedicated hand-shake signals. Additional daughterboards can be connected to a single motherboard to increase the number of channels.
