It let me connect directly to my project. It does not have any DB9 or DB25 if that’s what you are asking. A pigtail of individual wires was much more versatile. Yes, serial was one of them. I cannot guarantee what yours will have, I am not the manufacturer or distributor. **Q: where can I found the full config manual?** A: The unit comes with very basic manual, that provides an email to support for more in depth configurations. They answered all my questions thoroughly and fast, including sending the complete configuration manual with all the codes. I would recommend this item and the manufacturer. ## Frequently Bought Together - Maikrt Embedded QR Code Scanning Module USB and UART Serial Port Barcode Scanner Identification Module Bar Code Reader for Access Control, Locker Scan Code Payment etc - HiLetgo 1.3" IIC I2C Serial 128x64 SSH1106 SSD1306 OLED LCD Display LCD Module for Arduino AVR PIC STM32 - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/432776298-embedded-qr-code-scanning-module-usb-and-uart-serial-port](https://www.desertcart.co.uk/products/432776298-embedded-qr-code-scanning-module-usb-and-uart-serial-port) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-28*
