When we last checked in on the WiFiWart, an ambitious project to scratch-build a Linux powered penetration testing drop box small enough to be disguised as a standard phone charger, [Walker] was still in the early planning phases. In fact, it was little more than an idea. But we had a hunch that he was tenacious enough see the project through to reality, and now less than two months later, we’re happy to report that not only have the first prototype PCBs been assembled, but a community of like minded individuals is being built up around this exciting open source project.
Now before you get too excited, we should probably say that the prototypes didn’t actually work. Even worse, the precious Magic Smoke was released from the board’s Allwinner A33 ARM SoC when a pin only rated for 2.75 V was inadvertently fed 3.3 V. The culprit? Somehow [Walker] says he mistakenly ordered a 3.3 V regulator even though he had the appropriate 2.5 V model down in the Bill of Materials. A bummer to be sure, but that’s what prototypes are for.
Even though [Walker] wasn’t able to fire the board up, the fact that they even got produced shows just how much progress has been made in a relatively short amount of time. A lot of thought went into how the 1 GB DDR3 RAM would get connected to the A33, which includes a brief overview of how you do automatic trace length matching in KiCad. He’s also locked in component selections, such as the RTL8188CUS WiFi module, that were still being contemplated as of our last upd ..
