Here is what has been described as a development demo board running Python, which is unique in that it combines both an e Ink display and a Raspberry Pi RP2040 microcontroller. Designed by British company Pimoroni, the Badger 2040, as the device is named, has a small 2.9-inch monochrome e-ink display with 296 x 128 pixels. This gives a pixelated display but serves the purpose nonetheless. Additionally, as the name suggests, the Badger 2020 can be used as a personal identification badge at conferences or in the office.

Like the website Weekly Electronic reported, the Badger comes with 264KB RAM and 2MB QSPI Flash storage of which 1MB is reserved for the operating system and the remaining 1MB is available for storage. The front features five user-programmable buttons, while a white LED light doubles as an indicator. The back includes a reset button and a start button. The Badger does not, however, come with a built-in battery. Instead, there is the JST-PH connector for connecting the power source, which was specified as a 2.7 – 6V battery.

There’s also no built-in charger, although there is another power input option as well as a USB Type-C port for programming. Finally, there is the four-pin JST-SH Qwiic-STEMMA QT connector on board which is used for connecting I2C peripherals. As mentioned on the website, Pimoroni developed the C++ and MicroPython libraries, while it is also possible to program the device using CircuitPython.

“Our C++/MicroPython libraries contain some nifty software tweaks to help you get the most out of your Badger. You’ll get the best performance using C++, but if you’re a beginner, we recommend using our MicroPython version for easier startup,” the company said. “CircuitPython drivers are designed to work on a bunch of different microcontrollers so you won’t get the fancy RP2040 architecture-specific tweaks you’ll find in our library, but you will get access to all the conveniences of the Adafruit ecosystem.”

It’s worth mentioning that we’ve already seen a smart badge designed to translate and convert speech to text in real time.
