This module uses the NXP stack KW41Z for Thread and BLE and runs on an IPv6-based networking protocol to communicate on a local wireless mesh network. Thread uses 6LoWPAN, which uses the IEEE 802.15.4 wireless protocol with mesh communication. It is IP-addressable with cloud access and AES encryption.
The stack is able to support up to 250 devices in one local network. It is simple to set up and it provides security at the network layer. SPARROW includes an on board chip antenna and is supplied with a development board . An external antenna can be connected to the antenna pad.
