Badger 2040 W (Pico W Aboard) – PIM668
Badger W Only - A programmable badge with fast updating E Ink® display and wireless connectivity, powered by Raspberry Pi Pico W
Badger 2040 W is a maker-friendly all-in-one badge wearable, designed for efficient identification of humans and other lifeforms. It's great for powering by battery, as it can go into an ultra-low power sleep mode when the screen's not being refreshed. And because it's a handy microcontroller with built-in screen that can fit right in your pocket, we bet you could use it for a bunch of other cool experimental projects too.
On the front, you'll find the black and white 2.9" e-paper screen, a selection of buttons to poke at, and a slot to clip it onto a lanyard. On the back, there's a battery connector, a reset button, and a Qw/ST connector for plugging in Qwiic or STEMMA QT breakouts. And now that it's got a Raspberry Pi Pico W Aboard, it can communicate wirelessly with other devices and retrieve tasty data from the internet, hoorah!
What's new for Badger W
A bunch of improvements have been made to the OG Badger (in addition to the 2.4GHz wireless connectivity).
- Inspired by our other Pico W Aboard products, we've added an onboard RTC (Real Time Clock) so that Badger W can keep track of the time whilst it's asleep, and means it can wake up on a timer, as well as on a button press.
- Our C++/MicroPython software libraries for Badger W now use our in-house tiny graphics library, PicoGraphics. This means it's much easier to get images onto your Badger and code is simple to port between different Pimoroni displays.
- All the pre-loaded MicroPython BadgerOS examples now show up properly on Badger W's filesystem, so you can tinker with them easily - great for figuring out how things work! We've added a few new examples to BadgerOS that do wireless stuff.
Pico W x E Ink®
It makes for a lovely, crisp, high contrast display that's nice and readable, and it doesn't squirt unnecessary blue light into your environs like LCDs do. It's also ultra-low power (EPD displays only consume power while they're refreshing), and the images on the display stick around for a really long time whilst the display is unpowered.
Using a Raspberry Pico W means we can drive the hardware in fun, experimental, low level ways. We've written custom drivers for the EPD display that prioritise low power consumption whilst enabling lightning-fast refresh rates.
