Finished the schematic

What’s New

• Added the functionality of an oscilloscope
  • using the AD9283 ADC clocked at 50 MHz
• Cancelled the DAC (now only signal generation using the AD9833 for sine, square and triangle)
• Added the functionality to choose the voltage of the ISP programmer in software (with hardware safety)

Next Steps

• Double check the schematic
• Start PCB layout

TRACE Update 1

What’s New

• Defined architecture: two MCUs
  • RP2350 handles logic analyzer, programmers and function generation
  • ESP32-S3 handles WiFi, web UI and AI agent
• Selected key components: ADS1115 for voltage measurement,
  AD9833 for function generator, MCP4922 as DAC
• Started KiCad schematic — analog power section with split ground plane done

Interface

• WiFi: access from any device (phone, PC) via web UI
• USB: direct connection to host for PulseView (logic analyzer)
• AI integration: Claude agent to control the instrument
  • Describe your problem in plain language and Claude automatically
    measures and diagnoses it

Next Steps

• Complete ESP32-S3 and RP2350 schematics
• Start PCB layout
