The scanner 1 with a built-in LED, the Bluetooth module 2, the main control module 3, the display module 4 and the voice prompt module 6 are all connected to the main control module 3. The scanner 1 with a built-in LED captures a barcode or a QR code image and sends the image data to the main control module 3 for processing. The main control module 3 wirelessly communicates with an external device through the Bluetooth module 2. The display module 4 displays the scanning result. The voice prompt module 6 issues a sound prompt according to the instruction of the main control module 3. The power conversion module 5 supplies power to the scanner 1 with a built-in LED, the Bluetooth module 2, the main control module 3, the display module 4, the power conversion module 5 and the voice prompt module 6.

[0027] The built-in LED scanner 1 is primarily used to illuminate barcodes or QR codes for clearer image capture. This is crucial for improving reading accuracy and reliability, particularly in poor lighting conditions, effectively increasing the success rate and recognition accuracy of barcodes or QR codes. The built-in LED scanner 1 utilizes the Magellan 3200Vsi, which uses omnidirectional multi-line laser technology to capture barcodes or QR codes from multiple angles, thereby improving first-time read rates.

[0028] like Figure 2 As shown, the main control module 3 is a microcontroller U1, which is an STM32F103C8T6. The STM32F103C8T6 operates in a voltage range of 2.0V to 3.6V and operates in a temperature range of -40°C to 85°C. It features low power consumption and high speed operation. It also has a rich set of features, including but not limited to ADC, DAC, timers, and communication interfaces (such as UART, SPI, and I2C).

Resistor R10 is connected between pins 2 and 3 of Bluetooth chip U2, and resistor R11 is connected between pin 25 of Bluetooth chip U2 and the power supply VCC. Pin 31 of Bluetooth chip U2 is connected to pin 11 of microcontroller U1, pin 10 of Bluetooth chip U2 is connected to pin 12 of microcontroller U1, pin 36 of Bluetooth chip U2 is connected to pin 13 of microcontroller U1, and pin 37 of Bluetooth chip U2 is connected to pin 14 of microcontroller U1. Bluetooth module 2 is an ESP32-SL module, measuring only 18mm × 25.5mm, reducing hardware design complexity. Furthermore, the chip's sleep current is less than 5μA. The enable pin EN is connected to the 3.3V power supply via a 12kΩ pull-up resistor to ensure that the pin remains high unless explicitly pulled low.

[0030] like Figure 4As shown, display module 4 includes a TFT-LCD display. Pin 3 of the TFT-LCD display is connected to pin 42 of microcontroller U1, pin 4 of the TFT-LCD display is connected to pin 43 of microcontroller U1, pin 5 of the TFT-LCD display is connected to pin 7 of microcontroller U1, pin 6 of the TFT-LCD display is connected to pin 26 of microcontroller U1, pin 7 of the TFT-LCD display is connected to pin 27 of microcontroller U1, and pin 8 of the TFT-LCD display is connected to pin 28 of microcontroller U1. TFT-LCDs offer higher contrast, faster response times, and clearer displays. They provide clear image quality, typically with a resolution of 128x128 or higher. Depending on the compatibility of the control system, a serial interface (SPI) can be selected.

[0031] like Figure 5 As shown, voice prompt module 6 includes voice chip U3. Pin 9 of voice chip U3 is connected to pin 45 of microcontroller U1, and pin 10 of voice chip U3 is connected to pin 46 of microcontroller U1. Voice chip U3 is a WT588D chip, which performs the voice prompt function. The chip is responsible for outputting the voice file, and the speaker can produce audible prompts. Before using the WT588D chip, the voice resource must be downloaded. During the download, a circuit reset is required to synchronize the data. The WT588D has a built-in high-speed audio processor and a powerful D / A converter, supporting two output modes. The WT588DP03 port serves as the information input, which controls the entire chip. The PWM output terminal cannot be grounded. Port P15 is the output port for the busy signal. Before use, the busy signal must be checked to determine whether the module is currently processing other tasks. If the busy signal is low, it indicates that new data can be received; if the signal is high, it indicates that the module is currently busy.

[0032] like Figure 6 As shown, the power conversion module 5 includes a DC-DC chip U5, resistors R1 and R2, capacitors C1, C2, and C3.

The chip has an input voltage range of 2.7V to 5.5V and an output voltage range of 0.6V to 3.6V.

[0033] Built-in LEDs provide even and ample illumination, ensuring clear visibility of barcodes or QR codes in all lighting conditions. The scanner uses omnidirectional multi-line laser technology to capture barcode or QR code images from multiple angles. The captured image data is sent to the main control module via an interface for processing. The processed data is then transmitted to external devices via the Bluetooth module. The main control module can also receive instructions and data from external devices. The main control module receives and processes image data from the scanner, identifying the information contained in the barcode or QR code. Based on the processing results, it generates corresponding commands to control the display module and voice prompt module. Data is exchanged with external devices via the Bluetooth module. The display module receives display data from the main control module and displays the scan results, status information, or other necessary information on the screen for the user to view.

[0034] Following instructions from the main control module, preset voice prompts, such as "Scan successful" or "Please rescan," are played. The voice chip stores and manages voice files and outputs the sound through the speaker. The power conversion module converts the input 5V voltage into a stable 3.3V output, powering the scanner with built-in LED, Bluetooth module, main control module, display module, and voice prompt module. A filtering circuit composed of resistors and capacitors ensures the stability and reliability of the output voltage.
