Useful Sensors Tiny Code Reader

Useful Sensors Tiny Code Reader

Description: QR codes are a great way for users to communicate with microcontrollers, whether it’s passing WiFi credentials to set up connectivity or sending personal information to fill out a digital badge. Reading them from a maker project didn’t used to be easy though. You’d either needed a large and relatively expensive standalone module, or your own software solution on a board with a camera.

The Tiny Code Reader from Useful Sensors is smaller than a quarter, very low cost, and connects through Qwiic. This makes it the perfect add-on for all kinds of projects that could benefit from text input, but don’t have a keyboard or touch screen. Since QR codes are also easy to share over email, text, or even paper, they can also be used as passwords for access control on security-minded products.

It comes with a comprehensive developer guide, which includes example code for popular systems like Arduino, Raspberry Pi, Pico W, CircuitPython, and MicroPython, along with complete project tutorials for Wifi provisioning, keyboard input, and display updating.
