2. USB 2.0 host.
3. RJ45 with protection and two GPIO controlled LED.

The small dock is used to make the tiniest DIY router(29.0 x 27.0 x 21.4mm), it is not a breakout board…someone said my breakout board is ridiculous, now I can tell him, he made a mistake. 😀 That is never my real target from beginning.(but anyway, it can be used as a breakout board if you want 🙂 )

Really thank for my friend Zhiwei De 🙂 We will provide the 3D printer plastic shell blueprint later, then a very small router with SD card slot is born(and it can be used same function as PirateBox but a little more portable and more functions)
