Full Product Description

High-Performance Scanning in a Circular Form Factor

Most barcode modules are bulky and rectangular, making them hard to fit into modern, aesthetic designs. Our Round 2D Barcode Scanner Module (D) breaks the mold. Its circular design is not just for looks; it allows for easy "hole-punch" mounting in panels, making it perfect for elevator control boards and high-end access control systems.

Intelligent Image Recognition & Screen Scanning

Equipped with advanced CMOS image sensors and intelligent algorithms, this module excels where others fail. It quickly decodes complex 2D patterns and low-quality 1D barcodes. Whether your customers are scanning a printed ticket or a QR code on a high-brightness smartphone screen, the recognition is near-instantaneous.

Rugged, Reliable, and Ready for Integration

Built for industrial environments, the module operates reliably between -30°C and +70°C. The front side is IP54-rated, providing essential protection against dust and water splashes in public installations. The standard UART (TTL) interface ensures compatibility with popular microcontrollers like Arduino, Raspberry Pi, and ESP32, allowing you to go from prototype to production in record time.

FAQ Section

Q: Can this module be used with a 5V system?

A: The module requires a 3.3V power supply. If using with 5V logic (like an Arduino Uno), we recommend using a logic level shifter for the TX/RX pins to ensure long-term stability.

Q: Does it support scanning in dark environments?

A: Yes, the module features intelligent image recognition and can be configured for continuous or sensing modes to work effectively in various lighting conditions.

Q: How do I change the communication settings?

A: You can easily modify the baud rate and enable/disable specific barcode formats by scanning the Configuration Codes provided in the digital manual.
