
Main Board & Core Board
• Function
1. Control all peripherals of for acquisition of image data using FPGA and MCU.
- MCU and FPGA always communicate each other.
- Sensor reading status is transferred to the FPGA and to MCU.
- MCU and FPGA give a command to some peripherals such as Y-axis motor and Eraser unit etc.
2. All sensors on/off reading.
3. Convert analog signal to digital.
4. Provide Power to PMT, laser module, RFID board & some peripherals..
5. Transmit image data to PC using USB communication.
