Decode nearly any kind of 1D (striped) barcode in your project using this adorable compact barcode scanner. Adafruit have looked all over for a small, light, low-power module that can be easily integrated. This OEM scanner has a little camera inside that takes 100 photos per second, instead of using a 'scanning mirror' assembly. This means its less likely to get damaged or out of alignment.
Please note: this is a camera-based not laser-based scanner - you'll have to hold it farther away than you usually do for laser-mirror scanners! Try 10cm/4" or more distance with the button held down.
This all in one module is the most microcontroller-friendly Adafruit could find. It is powered over 5V and instead of a USB port, it has a PS/2 interface and acts like a 'keyboard'. In fact, its designed to be a 'pass through keyboard wedge' device for point-of-sale terminals. What's nice about PS/2 is that it uses a single connector for power and data, and uses two data pins. When a barcode is scanned, the raw data is decoded, parity-checked and spit out as if they were typed on a keyboard.
Like all barcode scanners, you can do some basic configuration by powering it up and 'scanning' in special barcodes in the manual. For example you can change the delay between 'typed' characters, or what the terminating character, if any, should be. Check the download tab for the printable manual. If you'd like to set up the scanner to be different than the default, print it out on plain white paper and scan each 'configuration' code. The config will be saved to non-volatile memory so you only have to do it once.
Nearly all microcontrollers have existing PS/2 keyboard examples that would work fine with this barcode scanner For Arduino users, Adafruit tried out PJRC's PS2_Keyboard library with great success - just check the 'simple text' example for which pins you can connect to on your 'duino (on an Uno Adafruit used digital pins 2 and 3). We suggest Adafruit's PS/2 adapter cable to make the wiring easy. Point the scanner's red image line at the barcode for automatic detection, data will be emitted automagically
This reader will read a wide variety of barcode standards. The most common ones such as CODE39 and UPC are supported out of the box. To enable some of the rarer standards, check the manual as you may have to 'scan configure' to enable it.
