MediVault

Smart Medicine Storage and Reminder System
Custom ESP32-Based PCB designed using KiCad 10

---

Overview

MediVault is a custom-designed smart medicine management PCB developed using KiCad 10.

The project provides an intelligent hardware platform capable of storing medicine schedules, monitoring environmental conditions, reminding users through visual and audible alerts, and controlling external mechanisms such as a servo-operated medicine compartment.

The PCB has been designed as a compact two-layer board suitable for fabrication and future firmware development.
