M32W wireless Internet of Things module is designed for the easy of programming and installation of IoT projects where a wireless protocol (zigbee, bluetooth, 433Mhz etc) is required. It is a plug-in module for MS14-S and powered by an AVR ATmega32u4 microcontroller.
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 Yûn compatible, it communicates with MS14-S CPU via SPI and UART interface and provide the power / GPIOs via the 14 positions screw terminal on MS14-S. M32W can be programmed by the latest Arduino IDE. The board type in Arduino IDE is "Arduino Yun".
With the combination of MS14-S, M32W and Arduino Yun software, users can install powerful Internet of Things projects that interface with i.e. XBee or RFM12B wireless sensors in an easy and quick 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.
- Easy programming use Arduino IDE.
- Program/update/ debug via WiFi network.

XBee Socket:
M32W has a standard XBee Socket. Any module compatible with this socket can be used directly in M32W.
RFM12B Footprint:
RFM12B footprint for HopeRF RFM12B module or RFM69CW/HCW 433/868/915 Radio module.
Prototyping Area:
A on-board prototyping area with power and Arduino pinout for easy prototyping.
Customized Screw Terminal:
When the M32W is used with MS14-S, the user can define the screw terminal connections by using the prototype area as shown above.
USB port debug/programming:
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.
