πŸ”Ή Optimized Compact UT Data Logger (STM32-Based)

Since you need a smaller, cooler, and more efficient system, we will replace the FPGA with a high-performance STM32 microcontroller while keeping high-speed ADC and UI capabilities intact.

πŸ”Ή Optimized Component Selection (Smallest Possible)

Component Recommended Part Why?
Microcontroller STM32H7 (480 MHz, 16-bit ADC, 4 MSPS) Fastest STM32 with DMA for real-time signal acquisition.
High-Speed ADC LTC2387-16 (16-bit, 15 MSPS, SPI) Compact, low-power, meets high-speed requirements.
Ultrasonic Transducer 5 MHz Miniature Piezo Transducer Compact and efficient for thickness measurement.
T/R Switch Miniature PIN Diode Switch (MA4P7470F-1072T) Low-loss, small footprint, protects receive circuit.
Pulser TC6320 (50V, Compact) High-voltage pulse generation in a small package.
Amplifier AD8421 (Low-noise, High-Gain Instrumentation Amp) Compact and efficient signal conditioning.
Display 3.5” or 5” SPI TFT Touchscreen Smaller alternative to a 7” screen for portability.
Enclosure Aluminum Mini Enclosure (100mm x 70mm x 40mm) Compact, lightweight, good heat dissipation.

πŸ”Ή Updated System Architecture

I will now create a new block diagram reflecting this smaller, STM32-based design. Give me a moment. πŸš€

It seems like I can’t do more advanced data analysis right now. Please try again later.

However, I can describe the updated compact STM32-based system in detail:

  1. Ultrasonic Transducer (5 MHz) β†’ Mini T/R Switch (MA4P7470F)

    • Switches between transmit and receive mode to protect the receiver.

  2. T/R Switch β†’ Compact Pulser & Amplifier (TC6320, AD8421)

    • Generates high-voltage pulses for the transducer.
    • Amplifies weak echoes before ADC conversion.

  3. High-Speed ADC (LTC2387-16, 15 MSPS) β†’ STM32H7

    • Converts analog echoes into digital signals.
    • STM32H7 handles real-time processing, FFT, and thickness calculations.

  4. STM32H7 β†’ Small TFT Display (3.5”-5”)

    • Displays real-time waveforms & measurement results.
    • Allows user interaction for settings & logging.

  5. Mini Enclosure (100mm x 70mm x 40mm)

    • Compactly integrates all components.
    • Ensures efficient power management & cooling.

Would you like help with wiring diagrams, PCB layout suggestions, or power supply design for this compact system? πŸš€

I can't create images directly, but I can describe a block diagram layout for you, which you can then draw using a tool like **Microsoft Visio, Fritzing, KiCad, or even pen and paper**. Here's the structure:

        ↓
[Mini T/R Switch (MA4P7470F)]
        ↓
[Pulser & Amplifier (TC6320, AD8421)]

Explanation of Each Block:

  1. Ultrasonic Transducer (5 MHz)

    • Sends & receives ultrasonic pulses.

  2. Mini T/R Switch (MA4P7470F)

    • Switches between transmit (TX) and receive (RX) mode.
    • Protects sensitive receiver circuits.

  3. Pulser & Amplifier (TC6320, AD8421)

    • Generates high-voltage pulses to drive the transducer.
    • Amplifies weak echo signals before ADC conversion.

  4. High-Speed ADC (LTC2387-16, 15 MSPS)

    • Converts analog echo signals into digital format.

  5. STM32H7 Microcontroller

    • Performs real-time signal processing, FFT, and thickness measurement.

  6. TFT Display (3.5” - 5”)

    • Displays waveforms, measurements, and user interface.

  7. Mini Enclosure (100mm x 70mm x 40mm)

    • Houses and protects all components in a compact form factor.

Next Steps:

  • If you need a visual block diagram, you can use draw.io (diagrams.net) or Visio to arrange these blocks with arrows.
  • Let me know if you want to modify the structure or add extra components like a battery/power circuit. πŸš€
