FREE-WILi OG

Embedded development tool for testing, debugging, and electronic system development
Portable interfaces, display, scripting, radios, and expansion in one handheld platform

FREE-WILi OG is the embedded development tool you have been waiting for. It is designed to simplify the process of testing, debugging, and developing electronic systems, while packing a wide range of interfaces and hardware features into one portable device.

It works equally well as a bench companion, a field instrument, a learning platform for embedded systems, and a nearly-finished development platform you can adapt for your own product or research workflow.
