Little Wire is a project by Ihsan Kehribar. It's kind of an ATtiny85-based USB Swiss army knife gadget that it can be used to implement a bunch of different hardware interfaces (parallel, I2C, SPI, ADC, 1Wire, WS2812, PWM, UART, AVR programmer) over a USB port. You can read more at the project website: http://littlewire.github.io/

I claim no credit for the electronics - I used the Eagle files on Ihsan's website to get a board made and then populated it - but I did think his project deserved a nice little case and came up with what you see here.

The two case halves are an intentionally snug fit but may require some adjustment depending on your printing conditions.
