The Smart Medicine Box is designed to ensure consistent medicine intake by patients. Using a dedicated smartphone app, users can setup their phones to display reminders, manage their personal medication status, and much more.

This reference design features the embedded RL78/G13 MCU which communicates with a Wi-Fi module via UART. The real-time clock (RTC) count value can be calibrated and the alarm time set or cleared from the Renesas IoT Sandbox via MQTT. Alarm time data is stored in the data flash. The ISL9120 high efficiency buck-boost switching regulator further enhances power control efficiency.
