Tildagon End User Manual

A hexagonal camp badge, with three smaller hexagonal PCBs containing breakout pins peaking out from the edges, and a screen showing @emfcamp

The Tildagon is a badge that you can wear around your neck. It has a round screen, six buttons, and lots of colourful LEDs. It has a USB-C connector, WiFi, and a battery. It can run MicroPython, and has six hexpansion connectors.

The badge will automatically connect to camp wifi, and you can use the app store to install apps.

The hexpansions that the badge supports allow you to extend the functionality of the badge with hardware made by yourself or other attendees.

Hexpansions

Slide a hexpansion into a slot on the edge of the badge until the connector tab is fully connected. The badge should detect it automatically and light up the port.

Inserting a hexpansion

Hexpansions must be 1mm thick to fit properly. If yours is not detected, see Detecting hexpansions.
