2D Barcode Scanner Breakout
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.
This breakout board makes it easy to explore all of the capabilities of the DE2120 without dealing with finicky flat flex cables. The scanner's USB interface is exposed via one of the two on-board USB-C connectors, the other is connected to the TTL interface through a CH340C USB-to-Serial bridge. A buzzer and status LED are connected to the module through appropriate drive circuits and a pushbutton tactile switch is provided on the "trigger" pin. When you're ready to incorporate the module into your embedded project, you can leverage the 5 pin header for direct access to the TTL serial pins, power pins, and trigger input.
The module can be configured either by using the serial interface or by scanning command barcodes found in the datasheet.

The github link is broken.
Sorry about that, the repo was still set to private. It should work now.
Looking at the schematic, it looks like there will be a conflict if you try to drive the RX header pin for embedded use, since it is also connected to the CH340C. I don't see a place on the schematic with a suggested cut point for that PCB trace. Should there be?
Hey! If you're having trouble with the CH340C pulling on the serial lines, you can clip the legs.
However I never experienced problems in testing. As long as you're not trying to drive the CH340 at the same time, it shouldn't interrupt the serial operation. If you think about it, the same was true of all early USB Arduino boards when using the hardware UART.
Hey there, as mentioned in the banner at the bottom of the product description, questions should be posted in the forum:
That being said, I am not sure if I understand the issue you are asking about. Are you referring to bus contention with the UART chip when using the breakout pins? You could possibly clip the legs of the CH340 chip or rework the chip, but those are the only alternatives I can come up with at this moment.
