Merkur Breakout Board

The Merkur Board was created for fast prototyping in the internet of things sector. It includes a 2.4GHz IEEE802.15.4 wireless chip, compatible with all 802.15.4 based protocols like 6LoWPAN, ZigBee and RF4ce. It supports Arduino and Contiki-OS

It's available at IoT-Shop

Thanks to the integrated Arduino-OSD boot loader it's possible to program the Merkur Board using a 3.3V FTDI USB-Serial converter.

only available in german at the moment.

The integration into the own IP network can be accomplished using a RaspyEdge-Shield, an Edge-Router or a Merkur Board with and FTDI USB-Serial converter. The Merkur Board automatically configures it IPv6 address based on the prefix given by one of the mentioned border routers. The Constrained Application Protocol (CoAP) is used on application layer.

There are multiple CoAP clients available.

* libcoap: C-Implementation of CoAP (with example command-line client) * Copper add-on for Firefox

CoAP on PC/RaspberryPi/Server

Coap on Android

 
 coap-client -m get coap://[2001:DB8::221:2eff:ff00:264e]:5683/.well-known/core
 coap-client -m get coap://[2001:DB8::221:2eff:ff00:264e]:5683/s/battery

The Merkur Board is shipped with preinstalled Arduino boot loader. It can be used with Arduino programs or Contiki-OS. Contiki-OS contains a tiny IP stack called uIP with an IPv6 and 6LoWPAN implementation. It's written in C and compiled through Make controlled cross compilers for the used hardware platform.
