Useful Sensors Tiny Code Reader

The Tiny Code Reader by Useful Sensors is a compact, cost-effective solution for integrating QR code reading capabilities into various projects. With its small size, comparable to a coin, and Qwiic connectivity, it’s an ideal addition for projects requiring text input without the need for a keyboard or touch screen.

QR codes offer a versatile way for users to interact with microcontrollers, whether it's for passing WiFi credentials or sending personal data for digital badges. Traditionally, reading QR codes in maker projects was challenging, often requiring bulky and expensive modules or custom software on a board with a camera. The Tiny Code Reader simplifies this process, making it accessible and affordable.

The device's small size and low cost make it suitable for a variety of applications. For instance, it can be used in security products to scan QR codes as passwords, providing an easy and secure method for access control. Additionally, QR codes can be shared effortlessly via email, text, or printed on paper, expanding the possibilities for their use in different scenarios.

To support developers, the Tiny Code Reader comes with a comprehensive developer guide. This guide includes example code for popular platforms such as Arduino, Raspberry Pi, Pico W, CircuitPython, and MicroPython. It also provides complete project tutorials for tasks like WiFi provisioning, keyboard input, and display updating, making it easier to get started with your projects.
