ETRX2-PA - Power Amplified Mesh Networking Module

The Telegesis ETRX2-PA offers boosted output power whilst being a drop in replacement for the standard ETRX2. Care was taken to retain the low deep sleep current to make this module ideally suited for battery operated end devices with the lowest transmit current in its class.

Based on the Ember EM250 single chip ZigBee solution utilizing EmberZNet 2.xx meshing technology, it has been designed for fast integration into any device without the need for RF experience and expertise.

Unlike many other module command layers the Telegesis AT-Style command set fully mirrors the functionality of the EmberZNet mesh networking stack.  With the ETRX2 module there is therefore no requirement for any embedded firmware expertise when engineering your mesh networking solution.
