The Tiny Code Reader from Useful Sensors is a small, low-cost RP2040-powered hardware module that reads QR codes. It's designed to be a simple way to provision a system, for example by providing the wifi network name and password, or to provide input when there's no keyboard.
Say goodbye to the days of requiring a standalone module or software solution on a microcontroller with a camera to read a QR code in your maker project.
QR codes are a fantastic way of communicating with microcontrollers, whether you’re passing Wi-Fi credentials to set up wireless connectivity or sending personal information to fill out a digital badge. This didn’t used to be simple though, you’d either need a standalone module which can be quite large and costly, or you’d need to develop a software solution on a microcontroller with a camera.
Those days are gone! Thanks to the Tiny Code Reader from Useful Sensors. So, what exactly makes this little gadget awesome?
Perfect add-on for projects needing text input
QR codes are an awesome way to share information over email, text, or even paper, they’re also great for using as passwords for access control security-minded projects. But if your project requires text input but has no touch screen or keyboard then the Tiny Code Reader is ideal, it simply connects through Qwiic.
Tiny form factor, cost-effective price
Designed with a compact form factor the Tiny Code Reader is the size of a coin so will easily fit in most places. Not only that, but it’s also cost-effective.
Compatible with many systems
The Tiny Code Reader comes with a comprehensive developer guide which includes example code for many popular systems including Arduino, Raspberry Pi, Pico W, CircuitPython, and MicroPython.
Project tutorials to help you get started
Aside from being compatible with many popular systems, there are also a number of complete project tutorials for Wi-Fi provisioning, keyboard input, and display updating so you can hit the ground running.
