4-Color BWYR Dithering Pipeline

Maps continuous RGB tones to Black (#000), White (#FFF), Amber Gold (#FC3), and Signal Red (#DB3727).

Attendee Identity & Handle

Customize the center orange card and bottom handle (replaces #WebAI with @rabimba).

1-Bit Pixel-Aligned QR Code

Zero-dither monochrome QR code placed below the name card so phone cameras scan instantaneously.

Second Screen Designer (programme.epaper)

Pressing physical BTN1 on the badge toggles between badge.epaper and programme.epaper. Use it as a giant scannable contact card, conference schedule, or full poster!

Wi-Fi Provisioning (wifi.json)

The badge firmware reads its network credentials from wifi.json in flash storage at boot. Write fresh credentials here over USB-C or BLE — transfer is CRC32-verified end to end. Password never leaves your browser except into the badge.

CRC32 Verified
No badge connected — connect via USB-C or BLE

Dynamic Connection Counter & .bootcde Patcher

The badge firmware dynamically overlays the white person silhouette and line count of scans.txt at bottom-left (8, 759) on every refresh.
