The SmartPen is a compact device designed to enhance productivity and memory retention. With a slim width of just 12mm, it incorporates a custom PCB for a sleek and efficient design. This device features an OLED screen, Bluetooth connectivity for seamless communication with PCs and smartphones, and a rechargeable LiPo battery with built-in protection and charging circuit.
The SmartPen is equipped with a system button for easy navigation and settings adjustment. It also has soldering pads for connecting a capacitive touch sensor and a pressure sensor to detect pen cartridge interaction. This allows users to interact with the device and navigate through different pages of stored information.
The primary function of the SmartPen is to assist with memory and organization. Users can send text strings via an app designed by a developer, which the SmartPen firmware processes and organizes into pages. This helps users keep track of important notes, dates, and names, enhancing their ability to recall information easily.
The schematic for the SmartPen outlines a compact and efficient design, featuring an ESP32-S3 microcontroller for core processing and Bluetooth connectivity. It includes a LiPo battery charging and protection circuit, a 3.3V regulator for stable power, and connections for an OLED display, system button, and cartridge switch. Key components are protected with ESD diodes and filtering capacitors, ensuring reliable operation and robust performance
