Dopo un po' di ricerche ho trovato un manuale dove sono presenti le istruzioni e i qrcode da scansionare per poter configurare il lettore secondo le proprie esigenze. A dire il vero, alcuni qrcode mancavano, per esempio quello per configurare la lettura in modo manuale alla pressione del tasto. Ho dovuto cercare il codice corrispondente (che si trova verso la fine della documentazione) al comando e farmi generare il corrispettivo qrcode da scansionare tramite un generatore online. Inoltre la documentazione non riporta che se il modulo viene resettato alle impostazioni di fabbrica, non manda più nulla in output (o quantomeno potrebbe farlo, a me è capitato che lo abbia fatto). Per far riprendere a mandare in output i valori dei codici letti su seriale o su emulazione tastiera in usb, si devono scansionare in ordine una serie di codici, corrisponenti ai comandi ~M00910001. ~M00510000. ~MA5F0506A. ~M00910000. Anche questi qrcode possono essere generati tramite un generatore online. Il fatto è che ho trovato per caso questa informazione su un altro sito che commercializzava il prodotto, dopo una intera giornata a sbattere la testa sui codici in C per arduino (che erano corretti) che non funzionavano proprio per questo problema che il modulo ha smesso di trasmettere ciò che leggeva. Eseguita questa configurazione, comunque, ha ripreso a funzionare correttamente. Do tre stelle proprio per la mancanza di un supporto documentale adeguato, per il resto il prodotto funziona e fa il suo lavoro in maniera più che dignitosa. ### ⭐⭐⭐⭐⭐ Easy. *by R***E on Reviewed in Germany on January 28, 2024* Funktioniert super und einfach. ### ⭐⭐⭐⭐ Produkt Top, Dokumentation eher verwirrend und nicht unbedingt Hilfreich *by C***D on Reviewed in Germany on September 8, 2023* Der Barcode Scanner funktioniert einwandfrei, bisher code ich klassiche Barcodes und QR Codes ohne Probleme scannen.Was ich nur schade finde, das die Dokumentation nicht wirklich aufzeigt wie man die Pins für die Verbindung verwendet, ebenfalls konnte ich die I2C-Adresse nicht finden daher habe ich es über die mittleren Bins verwendet die mit den Jumper eigentlich zwischen UART und USB switcht.(Ich verwende den Scanner für einen Arduino bzw ESP32)Ich konnte leider keine Configs finden zum scannen um den Scanner zu ändern, daher ebenfalls nicht so happy mit der Dokumentation. ## Frequently Bought Together - DollaTek UART Serial Embedded 2D Two-Dimensional Scanner v3.0 Engine Barcode Recognition Scanning Module Sweeping - Elegoo 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Wires Ribbon Cables Kit for arduino - Arduino Mega 2560 REV3 [A000067] – Advanced Microcontroller Board with ATmega2560, 54 Digital I/O Pins, Expanded Memory for Large Projects, Ideal for Robotics & Automation --- ## 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/303591285-uart-serial-embedded-2d-two-dimensional-scanner-v3-0-engine](https://www.desertcart.co.uk/products/303591285-uart-serial-embedded-2d-two-dimensional-scanner-v3-0-engine) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-25*
