M32W

M32W wireless Internet of Things module is designed for the easy of programming and installation for IoT projects where wireless protocol (zigbee, bluetooth, 433Mhz etc) is required. It is a plug-in module for MS14 and powered by an ATMEL ATmega32u4 micro-controller.

The M32W has a standard XBEE Socket and RFM12B footprint to implement different wireless protocol modules. It also has a breadboard area for easy prototyping.

M32W is Arduino Yun compatible. It can be programmed and debug by the Arduino IDE(ver 1.5.4 or later) via WiFi.

With the combination of MS14, M32W and Arduino Yun software, user can install / prototype Internet of Things projects in an easy / rapidly way. 

Features:

Bridge various wireless protocols such as zigbee, bluetooth, NFC into WiFi IP network.

Internet of Things Gateway module to connect sensor network to internet.

Log sensor data and upload to remote server.

Control switch/relay from Internet.

Arduino IDE compatible, can be programmed /debug by Arduino IDE. 

Program/update/ debug via WiFi network.

Customized Screw Terminal

screw terminal connections

While M32W is used with MS14-S, user can define the screw terminal feature by using the prototype area as shown above. Which gives more flexible/ possibility for prototyping.

 

USB port debug/programming

USB debug

M32W has a micro USB connector and can act as standard USB COM device. This USB connection can be used to upgrade sketch or debug the software via serial monitor on Arduino IDE.
