6LoWPan and ZigBee IoT Module

wi502 module iot 6lowpan zigbee

IoT Communications over 2.4GHz ISM band

The WI502 is a sensory node (called Mote or Sensor Node) developed for wireless sensor networks standard IEEE 802.15.4, 6LoWPAN and ZigBee compatible.

The sensors on the card or addable through the expansion connector allow the measurement of different physical parameters to be used in different application fields.

Its internal architecture is well explained in the block diagram below.
