STMicroelectronics L99H02QF Evaluation Board

STMicroelectronics L99H02QF Evaluation Board is designed for DC motor control in automotive applications. The L99H02QF is composed of a motherboard and a daughterboard on which the L99H02QF is pre-assembled. The motherboard, based on the STM8A microcontroller, provides the logic section for monitoring and driving the L99H02QF assembled in the daughterboard. ST provides dedicated user-friendly software with a Graphic User Interface (GUI) to make board usage and settings simpler. This allows setting L99H02QF parameters and registers, simultaneously showing real-time device diagnostic information like motor evolution, free-wheeling, board temperature, and much more.
