Description
Little Wire is multi-featured USB controlled open source hardware tool packed in a minimal form factor designed by ihsan Kehribar. Even though it has minimal form factor, and packed with full of features; there aren’t any SMT components involved, therefore it is very suitable for beginners to assemble.
This tool has to take instructions at run-time over USB. It can't work in a computer-less environment.
Note
V1.1 beta firmware released for the Little Wire. You can find the changelog and details from this link.
Features
- USB controlled multi-tool with:
- 4-channel digital input / output
- ADC (10 bit resolution)
- 2 parallel hardware PWM outputs
- SPI interface
