DigiKey is the best!
I try to maintain inventory of parts. This needs a search for component information with either the manufacturer part number or the DigiKey part number. Some of these fields are much longer than what you can quickly type, hence a simple tool to decode the barcode.

This software reads the barcode string from DigiKey Product2DBarcode on the anti-static bag. The barcode scanner is assumed to be connected as a Virutal COM port device.
Following image shows an example of such a barcode:
I have configured my barcode scanner to read upto last five zeros and it also sends type of barcode as prefix ]d1[. Actual barcode information starts with [)>, including.
Barcode string in Python's byte format is as follows:
b']d1[)>\x1e06\x1dP4463-D1CPC0306QR050FF-T50CT-ND\x1d1PD1CPC0306QR050FF-T50\x1dK202301100001\x1d1K79514818\x1d10K94852328\x1d11K1\x1d4LCN\x1dQ10\x1d11ZPICK\x1d12Z16735650\x1d13Z924360\x1d20Z00000'
Header is [)> and each field seems to be separated by a space or a period.
Decoded fields follows after the header, each field has prefix indicating type and perhaps maximum length:
| Useful | Field | Prefix | Value |
|---|---|---|---|
| Yes | Part Number | 06P | 4463-D1CPC0306QR050FF-T50CT-ND |
| Yes | MFG Part Number | 1P | D1CPC0306QR050FF-T50 |

| No | Country of Origin | 4L | CN |
| Yes | Quantity | Q | 10 |
| No | Unknown | 11Z | PICK |

The barcode can be used along with DigiKey's web API to obtain information in JSON format. More information at https://developer.digikey.com/products/barcode/barcoding/product2dbarcode. Supported Barcode Scanner:
- Honeywell N5600 camera based scanner with USB interface in COM emulation mode.
- Python Version tested on: 3.11
- OS Supported: Linux or macOS
-
Clone the repository.
-
Create Python virtual environment with:
python -m venv <path where to create>e.g.
python -m venv ~/.virtualenvs/digikeybarcode. -
Activate virtual environment using:
-
Install the dependencies using
pip install -r requirements.txt. -
Run the program using:
python src/user_interface.py.
- Connect the USB barcode scanner to the computer and make sure it works beforehand.
- When the software starts, it will scan for COM ports with product ID N5600 and selects it.
- Then the empty user interface (UI) is loaded which shows selected virtual COM Port as follows:
Ready your DigiKey pack with barcode. When you press Enter or click on Scan Barcode button, the scanner will trigger scanning mode. Once it scans it will be a couple of seconds before the data gets filled into the text boxes.
By default, the Part ID is automatically copied to the System Clipboard.
