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. Features 2.4" colour IPS LCD display (320 x 240 pixels) Driver IC: ST7789v Connected via parallel Dimmable backlight (adjustable via PWM) Powered by RP2040 (Dual Arm Cortex M0+ running at up to 133Mhz with 264kB of SRAM) 8MB of QSPI flash supporting XiP Phototransistor for light sensing Five front user buttons Power and boot buttons (the boot button can also be used as a user button) White LED USB-C connector for power and programming JST-PH connector for attaching a battery (input range 3V - 5.5V) High-precision voltage reference for battery level monitoring.
