Install / Re-install

Use Chrome or Edge on a desktop, plug the Cardputer in via USB, then:

No toolchain needed — this flashes the firmware straight from your browser. If the button is greyed out, your browser doesn't support Web Serial (try Chrome/Edge).

After flashing — set up your station

  1. Call & grid: press M → 4 (Call), 5 (Grid).
  2. IC-705 link: press O, then ▼ to the WiFi page — 1 SSID, 2 WiFi Pass, 3 Net User, 4 Net Pass, 5 CI-V.
  3. Connect: press S → 2.

Settings persist across reboots (stored in NVS). Full radio-side setup and the operating manual are in the README.
