The Grow GM78 Barcode Scanner utilizes a high-performance 640×480 pixel CMOS image sensor for precise optical capture of 1D linear and 2D Matrix barcodes. Its imaging engine achieves a minimum element width (MEW) resolution of 4mil, enabling reliable reading of high-density and damaged codes. The module outputs decoded data via a selectable USB 2.0 (emulating HID keyboard or virtual COM port) or UART TTL serial interface, providing plug-and-play compatibility with PCs, microcontrollers (Arduino, Raspberry Pi, ESP32), and industrial PLCs.
Engineered for embedded applications, the GM78 features a compact, board-level form factor ideal for integration into kiosks, vending machines, inventory tracking systems, and portable data terminals. Its robust decoding algorithm supports an extensive library of symbologies, ensuring versatility across retail, logistics, and manufacturing environments. The scanner operates within a typical reading distance range of 25mm to 200mm, balancing field of view with depth of field for consistent performance.
