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 an RL78/G1D BLE module via UART. The ISL9120 high efficiency buck-boost switching regulator further enhances power control efficiency.
