HW-1268 TTL barcode QR scanning module supports almost all common 1D bar codes and 2D QR codes, such as code128, code39, QR, PDF417, Datamatrix etc. It has extremely low power consumption, can be set to sleep mode, and supports TTL/USB signal via 12pins FFC cable.

TTL barcode QR scanning module

A serial communication interface is a common way of connecting an engine to a host device. When using the serial communication interface, the communication parameter configuration between the engine and the host device must be completely matched to ensure smooth communication and correct data. The serial communication interface provided by the engine is a TTL level signal. The TTL232 format can be connected to most application architectures, but when the RS-232 format must be used, an external conversion circuit needs to be added. The baud rate, Parity Type, Data Bits, and Stop Bits of the TTL serial port can be set.

This product supports TTL serial communication, the TTL signal is 3.3VDC high and low level (the power supply of this product is also 3.3VDC±5%), a two-way communication method, scanned data can be output through the TX port, and can also receive external commands through the RX port, according to the received command, the engine takes the corresponding action.
