HackSpace Magazine Issue 72 compares the Tiny Code Reader from Useful Sensors with the Zero Barcode HAT. About the Tiny Code Reader:
This is the product that inspired the entire roundup. The Tiny Code Reader from Useful Sensors is available at Adafruit. It has an RP2040 on the back and a camera module on the front. It allows you to quickly scan a QR code and feed the data into a microcontroller or single board
computer. And it’s really inexpensive! Just $7!The on-board microcontroller runs TensorFlow Lite and does some complicated image recognition to decode the QR code. Simply connect it to your microcontroller via the STEMMA QT / Qwiic connector or wire it up the old-fashioned way. It’s amazing to think about this $7 technology compared to what was available ten years ago. We are in the future!
HackSpace Magazine awards the Tiny Code Reader a 10/10, saying “Amazing tech at an amazing price.”
