Trellis is an open source backlight keypad driver system. It is easy to use, works with any 3mm LEDs and eight tiles can be tiled together on a shared I2C bus.
Enclosure design features ports for USB and power. Bottom cover includes mounting holes for Arduino board. The tray piece holes the trellis driver PCB into place, allowing enough room for jumper wires. Snap tolerances are optimized for PLA, but should also work for ABS and SLS.
Great for MIDI instruments, drum sequencers, puzzle games and more!
Tutorials on the Adafruit Learning System featuring an Introduction to Trellis
Adafruit was founded in 2005 by MIT engineer, Limor "Ladyada" Fried. Her goal was to create the best place online for learning electronics and making the best designed products for makers of all ages and skill levels. Since then Adafruit has grown to over 25 employees in the heart of NYC. We've expanded our offerings to include tools, equipment and electronics that Limor personally selects, tests and approves before going in to the Adafruit store.
