Hi Sir,
My customer is designing for smart lock for hotel or locker. MCU will be used to communicate with wifi chip (Espressif ESP-WROOM-02) as a peripheral and to control motor driver (DRV8832).
Currently they are considering STM32F0 M0 MCU. I am trying to promote MSP430. Customer target price is USD0.5. Is there any recommendation part from MSP430 which can be designed for this application?
Thanks. Hope to hear from you soon.
