This new member of the Raspberry Pi family may surprise you.
With its tiny form factor (around 7 cm x 3 cm) and a relatively good variety of I/0 interfaces, this device promises to bring processing power and radio heterogeneity to Wireless Sensor Networks (WSN) and IoT deployments.
It is not risky to affirm that using the Pi Zero W as a sensor node can open a lot of opportunities. From taking advantage of the USB OTG to plug additional wireless communication interfaces (like LTE, LoRa, or others), to install Open vSwitch (OVS) and manage the networking operation of the device via a Software Defined Network (SDN) OpenFlow Controller; the Pi Zero W can handle it.
As exploration on the applications of this tiny yet powerful device continues, it is considered a great tool for prototyping. Give it a try.
