The B-G473E-ZEST1S Discovery kit is a part of the motor-control development platform supporting ZeST and HSO algorithms. B-G473E-ZEST1S is a control board with the STM32G473QET6 microcontroller in the ZeST Discovery pack and works together with a Power board such as STEVAL-LVLP01, an optional adaptor board such as B-ZEST-ADAPT1, and an accessories package such as B-MOTOR-PMSMA1. The B-G473E-ZEST1S control board is connected to the power board or adaptor board through an embedded MC connector V2. B-G473E-ZEST1S can also support motor driver expansion boards X-NUCLEO-IHM08M1, X-NUCLEO-IHM09M1, and X-NUCLEO-IHM16M1 via the Morpho MC connector. STLINK-V3EC is integrated into the board, as an embedded in-circuit debugger and programmer for the STM32 MCU and the USB Virtual COM port bridge. The STM32 ZeST algorithm is available for selected users only.
