I need to deploy small mesh network.
My requirements are
* Minimum 802.15.4 MAC should be there.
* Board should have Many GPIO for users.
* Good to have have USB( or UART) interface. (Minimum PAN coordinator should have host interface, remaining can be without host interface)
* Good to have few sensors on board (Not must)
* Low cost
* debugger
* gcc compiler
Can anyone suggest the hardware that will suit my requirement.
