A hackable, programmable badge with 2.4″ (320 x 240) TFT LCD colour display, powered by Raspberry Pi RP2040.
We’ve had a lot of requests for a LCD version of Badger 2040 so tada – meet our pal Tufty. In a nutshell, we’ve combined a RP2040 microcontroller with a nice, crisp LCD screen to make a snazzy, colourful programmable badge – perfect for identifying/expressing yourself at cybernetic conferences, illicit undersea research facilities or dodgy space station bars. Don’t limit yourself to hanging it round your neck (or tail) though, use it as a sleek display/control panel for sensor readouts, a photo frame for digitally generated art or for making/playing small games. Perhaps you could even have a crack at making it play Doom?
Tufty comes fully loaded with a quintet of buttons so you can easily change what’s displayed on the screen, a slot so you can clip it onto a lanyard and a light sensing phototransistor, which can be used to adjust the brightness of the screen automatically. On the back, you’ll find a ✨majestic cyberpunk squirrel✨, a battery connector (with a nice wide input voltage) and the usual RP2040 old chestnuts – boot and power on/off buttons and a Qw/ST connector for attaching breakouts.
You can pick up a Tufty on its own, or for a bit more cashew can get a handy Tufty + Accessory Kit with a lanyard, AAA battery pack and USB cable.
