Mihini/Developer Kit

This page collect ideas for what will eventually become an official Mihini/M2MIWG developer kit. The aim of such a kit is to provide all the required H/W for running and evaluating Mihini. It has to be available from virtually any electronics reseller, and at a very affordable price (< 50USD?)

Features

• The dev. kit must be repurposable, i.e it must be able to act as a Modbus device, CAN Bus device, ... depending on the solution the developer wants to prototype.
• The dev. kit must be available both in the form of a kit (cheapest form), and pre-assembled
• The dev. kit must include enough built-in physical inputs and outputs to make it more useful than just "push the button/blink a LED". List of interesting -yet relatively cheap- inputs include: temperature sensor, light sensor, (heartbeat sensor??). Outputs: LCD display, buzzer (?), ...
• The dev. kit should have a handful of Grove-like (http://www.seeedstudio.com/wiki/GROVE_System) connectors so as it is possible to plug external sensors easily (e.g. an heart-rate earclip)

Proposed solution

In order to propose a repurposable dev. kit, it would be good to rely on an Arduino coupled to a dedicated shield giving serial (is Arduino serial enough or do we want RS-232/DB-9 too?) connectivity, holding a temperature and humidity sensor, and allowing to connect external buttons and display using a Grove connector.
