MikroTik mAP lite
The mAP lite, or RBmAPL-2nD, is equipped with a 650MHz processor, 64MB RAM, one fast ethernet port and a 802.11b/g/n wireless module. It can be powered with a separate power adapter or by PoE. The micro USB connector allows powering the mAP with a standard USB cable, so you can power it with your laptop!
A nice additonal feature is the magnetic back. You can simple attach it to any metal object, for example a rack. With the provided adhesive mounting plate, you can even attach it to non-metal objects!
What I use it for
My mAP is configured to be part of the jumpNet. I use it in my car for project I'm going to show you in near future ;-)
