ΠΕΡΙΓΡΑΦΗ

Tufty 2040 is a LCD version of Badger 2040! In a nutshell, Pimoroni 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 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.

Notes

  • Measurements: 65.2mm x 52.7mm x 9.6mm (L x W x H, including connectors). The mounting holes are M2 and 2.9mm in from each edge. The corner radius is 3mm.
  • We've designed Tufty 2040 to be accommodating about input voltage (3V - 5.5V), so it's possible to use a variety of different batteries and battery packs. We'd recommend using a 3x AAA battery pack which should give you maximum juice whilst still fitting behind Tufty nicely.
  • A 2x AAA battery pack will only work well if you use non-rechargeable batteries - the voltage from 2 rechargeable (NiMH) batteries (2.4V) is just not enough for the screen.
  • Tuftys are hungrier than Badgers! Power consumption is around 80mA for the screen (at full brightness) and 20mA for the RP2040 - so 100 mA total. Tufty has a toggle power on / off button (instead of a reset button) to make it easy to turn it off to preserve power, and setting the backlight to dim/turn off automatically will also make your batteries last much longer.
  • Alternatively, you can plug a LiPo/LiIon battery into the battery connector, with the following caveats. Please only consider this if the person wearing the badge is an adult and knows what they're doing with LiPos!
    • A solid enclosure or backplate to protect the battery from damage whilst being worn is a very good idea 
    • There's no battery protection included on Tufty 2040, so you should only use it with LiPo batteries that include internal protection
    • Unlike some of our other boards, Tufty 2040 doesn't have battery charging circuitry onboard. You'll need an external LiPo charger to charge the battery

  • Qw/ST (Qwiic/STEMMA QT) connector
  • Fully-assembled (no soldering required)
  • Schematic
  • Dimensional drawing
  • C++/MicroPython libraries

Software

You can program Tufty with C/C++ or MicroPython. You'll get best performance using C++, but if you're a beginner we'd recommend using our batteries included MicroPython build for ease of getting started. We've preloaded Tufty with a demo reel of fun examples to show you what it can do!

The display functions in our new improved PicoGraphics library have been given a glow up - be sure to check them out! You can now:

  • render JPEGs
  • display QR codes
  • draw weird polygonal shapes
  • import sprites from a spritesheet
  • use custom colour palettes (saving valuable RAM)

ΔΥΝΑΤΟΤΗΤΕΣ

Connecting Breakouts

The Qw/ST connector on Tufty 2040 makes it super easy to connect up Qwiic or STEMMA QT breakouts. If your breakout has a QW/ST connector on board, you can plug it straight in with a JST-SH to JST-SH cable.

Breakout Garden breakouts that don't have a Qw/ST connector can be connected using a JST-SH to JST-SH cable plus a Qw/ST to Breakout Garden adaptor. Want to use multiple breakouts at the same time? Try this adaptor!
