The XTIOT XT206M1 is a compact embedded barcode scanner module that supports 3.3V TTL communication. It can be integrated with Raspberry Pi boards and other embedded controllers that use compatible UART signal levels.

This makes it suitable for equipment developers who want to add 1D and 2D barcode scanning to a Raspberry Pi-based device.

5V Power and 3.3V TTL Communication

A common source of confusion is the difference between the scanner’s power supply and its communication signal level.

The XT206M1 uses:

• 5V power input

• 3.3V TTL communication signals

The 3.3V specification applies to the TTL communication interface. It does not mean that the scanner should be powered by a 3.3V supply.

UART Communication with Raspberry Pi

The XT206M1 can communicate with a Raspberry Pi through the UART interface when the signal levels and communication settings are compatible.

The host can receive decoded barcode data and, when required, send supported control commands to the scanner.

Before connecting the hardware, the customer should confirm:

• Scanner power requirements

• Raspberry Pi model

• UART signal level

• Connector and pin definition

• Baud rate and serial format

• Required trigger method

The final wiring must follow the confirmed pin definitions for both devices. It should be checked by the customer’s hardware engineer before power is applied.

Compact Module for Embedded Equipment

The XT206M1 measures 40 × 20 × 11 mm and weighs approximately 4.8 g. Its compact design allows it to be installed inside:

• Raspberry Pi kiosks

• Prototype terminals

• Access devices

• Desktop equipment

• Small automation systems

• Custom data collection devices

The module can read common 1D and 2D barcodes from printed labels and electronic screens.

Multiple Interface Options

In addition to 3.3V TTL, the XT206M1 can be supplied with USB or RS232 communication options for different host systems.

The required interface should be confirmed before ordering because the cable, connector and hardware configuration may vary.

Host Software Development

XTIOT supplies the barcode scanner hardware, communication information and supported command details.

The customer is responsible for developing the Raspberry Pi application, receiving the decoded data and connecting it to the required database or business system.

Information Required Before Ordering

Please provide the following information for model and interface confirmation:

1. Raspberry Pi model

2. Required communication interface

3. Actual barcode samples

4. Installation space

5. Trigger method

6. Connector or cable requirements

7. Estimated order quantity

XTIOT can test the actual barcode samples and confirm the appropriate XT206M1 hardware configuration.

FAQ

Does the XT206M1 support Raspberry Pi?

Yes. The XT206M1 supports 3.3V TTL communication and can be integrated with compatible Raspberry Pi UART hardware.

Does 3.3V TTL mean 3.3V power input?

No. The XT206M1 uses 5V power. The TTL communication signals use 3.3V logic.

Does XTIOT provide Raspberry Pi software?

No. XTIOT supplies the scanner hardware and communication information. The customer develops the host application.

Can the connector or cable be customized?

Connector type, cable length and pin definition can be confirmed according to the order requirements.
