ADVANCED TOOLS
Right now, this device only works because your browser tab is open.
Trial mode needs a live connection back to this page. Close the tab, lose signal, or switch away for too long, and your device locks — mid-shoot, if that's when it happens. A license key removes that dependency completely: a one-time signed certificate gets written directly to your device, and it runs 100% offline, forever. No tab. No Wi-Fi. No Lab.
- → Permanent offline activation — no heartbeat, no browser tab, ever again
- → One signed key, valid for the life of the device
- → Priority access to new firmware as Phase 2 ships
- Browser: Chrome or Edge on desktop
- Cable: USB data cable (not charge-only)
- Close tools: Arduino IDE / PlatformIO / other serial monitors
- Driver: CP2102/CH340
