A smart interactive badge with four-level greyscale 2.7" E-Paper display, powered by Raspberry Pi RP2350.

Badger 2350 is an all-in-one badge wearable with a fast updating 2.7" electronic paper screen, built-in rechargeable battery and sturdy polycarbonate case. Hang it round your neck with the (included) Badger lanyard or prop it up on your desk - either way it's ready to go straight out of the box. It's way more than just a event badge too - the four-level greyscale screen would also be great for displaying charts, signage or QR codes.

🌳 What is Badgeware?

Badgeware is a trio of all-in-one wearables designed to put customisable tech within everyone's reach.

Each species of badgeware is built around a different display, but they share the same common features - five sturdy front buttons, a translucent jewel-coloured polycarbonate case and a built-in LiPo battery with USB-C charging. They also have rear mounted mono lighting to illuminate the case. Under the hood is top notch Raspberry Pi hardware - a capable dual core RP2350 chip plus a RM2 radio module for wireless and Bluetooth connectivity.

They're easy and fun for beginners to get started with, yet powerful enough for experienced coders to really make their own. Connect your badge to any computer to quickly personalise our apps, or use MicroPython to develop new ones and add them to the BadgeOS launcher.

📦 What's in the box?

Every Badger 2350 comes fully assembled in a sturdy case with a built-in battery and a snazzy matching lanyard. You'll need a USB-C cable to charge the battery and program Badger (if you don't have one already, we stock USB-A to USB-C cables here).

The STEM Kit also includes a cute controller and some fun (but educational!) sensors to play with. It contains:

Badger 2350 (+ case and lanyard)
Qw/ST Pad (a tiny I2C game controller)
Multi-Sensor Stick (an all-in-one super sensor suite for environmental, light and movement sensing)
2x Qw/ST cables to connect everything up
