A desktop scanner probes a connected microcontroller’s buses and pins, then turns the measurements into a report for an AI coding chat.

Landing page captured for the 2026-08-28 issue.

Field notes

The workflow combines a one-time firmware upload with a two-click desktop scan after the board is connected. The scanner checks I2C addresses from 0x08 through 0x77, samples GPIO pins under both pull states, reports calibrated ADC voltage, reads OneWire’s 64-bit ROM code, and listens for UART data at 9600 or 115200 baud. For unidentifiable parts, the page says it preserves raw bytes rather than assigning a guess.
