The DYScan DE2120 is one of the coolest little barcode scanners we’ve ever seen. This tiny “scan engine” will read 20 different barcode symbologies — both 1D and 2D! This is achieved by using a camera coupled with on-board image processing to identify and decode everything from UPC codes to QR codes. The module also features two LEDs: one for illumination and one to project the red line that you’re used to seeing from laser-based scanners.
On a hardware level, this bare module is a little difficult to connect to. It comes with a 12-position 0.5mm flat-flex cable, so you’ll need the mating connector (unless you want to spend some quality time with a soldering iron and some very fine wire) But on a software level, it couldn’t be easier to interface with. There are two interface options: TTL Serial and USB. The USB interface will operate in Full-Speed HID mode. Keyboard emulation mode, or even virtual serial mode.
The module can be configured either by using the serial interface or by scanning command barcodes found in the datasheet.
