EV-VNH7100BAS Evaluation Board STMicroelectronics EV-VNH7100BAS Evaluation Board is used to connect STMicroelectronics® VIPower® M0-7 H-Bridge drivers into existing prototype circuitry. The STMicroelectronics EV-VNH7100BAS Evaluation Board is preassembled with the VNH7100BAS H-Bridge. An on-board minimum set of electrical components allows for directly connecting the load, power supply, and microcontroller without additional effort in external component design and connection.
