Name: GROW GM812 Series DC5V USB/UART Interface Barcode Scanner Module Reader for Arduino Android Windows
SKU: 2356421

Product Introduction

GM812 series have GM812-S and GM812-L model.

The only difference between GM812-S and GM812-L is the lens.

GM812-S lens reading distance is 5-30cm.

GM812-L lens reading distance is 7-50cm.

(The actual data depends on the size and content of the code)

GM812 series bar code reader module is a high performance scanner, can read 1D bar code easily and read 2D bar code with high speed. It also wins high scan speed for linear code, even for bar code on paper or screen.

GM812 series bar code reader module is an advanced bar code decoding algorithm which developed on image recognition algorithm, can easily and accurately read bar code, simplify secondary development.
