Nightmare has come 🙁  .OK , let’s back to our topic today. Remember i ‘ve introduced the XBee modules last week? it is just a general introduction, now, i will introduce them respeactively, and for todays post, we will take a look at the SERIES1 modules.

This is a popular 2.4GHz low-power XBee module from Digi. These modules use the IEEE 802.15.4 networking protocol (the basis for Zigbee) for fast point-to-multipoint or peer-to-peer networking and wrap it into a simple to use serial command set, and these usually referred to as S1 modules. They are designed for high-throughput applications requiring low latency and predictable communication timing. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.
