Description
The EVAL-L99DZ100G and EVAL-L99DZ120 are evaluation boards designed for Door Zone
Applications. Both are composed by the same motherboard and they differentiate for the
daughter board on which is pre-assembled the L99DZ100G in the EVAL-L99DZ100G case
(conceived for front door application) or the L99DZ120 in the EVAL-L99DZ120 case
(conceived for rear door applications).
The motherboard, based on STM8 microcontroller, provides the logic section for monitoring
and driving the L99DZ100G or the L99DZ120 assembled in the daughterboard.
With aim of making the board usage and settings simpler, ST provides a dedicated and a
user-friendly software with a Graphic User Interface (GUI). This enables the user to set
L99DZ100G or L99DZ120 parameters and at the same time it shows real time device
diagnostic information as the current output evolution, the battery voltage monitoring, the
board temperature and much more.
