Save the Multitools!
The Flipper Zero helped popularize the idea of a pocket-sized electronics multitool, combining several tools that hardware hackers and security researchers might otherwise carry separately. But there is a lot more that can be squeezed into a handheld device, especially if you are willing to sacrifice a little pocket space. FREE-WILi 2 takes that approach, packing enough hardware into its enclosure to serve as something closer to a portable electronics lab.
FREE-WILi 2 is built around a pair of Raspberry Pi RP2350 microcontrollers. One acts as the main processor for I/O and scripting, while the other handles the 3.5-inch, 480×320 capacitive touchscreen, controls, audio, and DVI output. Each RP2350 gets 8 MB of SRAM and 16 MB of flash.
That’s already quite a bit of processing horsepower for embedded projects, but the designers didn't stop there. There is also a Lattice iCE40UP5K FPGA with another 8 MB of SRAM. It...
