Badger 2350 is an all-in-one wearable badge built around a fast-updating 2.7" four-level greyscale electronic paper display. It arrives fully assembled in a sturdy polycarbonate case with a built-in rechargeable battery, so it can be worn on the included lanyard or propped up on a desk for signage, charts, QR codes or badge apps.
This STEM Kit includes the Badger 2350 with its case and lanyard, a Qw/ST Pad tiny I2C game controller, a Multi-Sensor Stick for environmental, light and movement sensing, and 2x Qw/ST cables to connect everything up. You will need a USB-C cable for charging and programming if you do not already have one.
Badgeware is designed to be approachable for beginners while still giving experienced coders room to customise. Connect it to a computer to personalise the included apps, or use MicroPython to develop new ones and add them to the BadgeOS launcher.
The built-in I2C connector is compatible with Qwiic/STEMMA QT breakouts via JST-SH cabling, making it easy to expand the badge with sensors and other modules.

Badgeware documentation plus MicroPython firmware and examples are available from Pimoroni for getting started and building your own apps.
Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- MCP73831
- A lithium battery charger chip used to safely charge a single-cell LiPo battery. It matters because it lets the board recharge a battery from USB or another input without needing a separate charger module.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- SRAM
- Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
- SWD
- Serial Wire Debug is a two-wire programming and debugging interface used with many microcontrollers. It matters if you need low-level access to program, recover or debug the processor board connected to this carrier.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
