ETRX2-PA ZigBee Module with Power Amp

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.

Module Features

• Small form factor, SMT module 37.75 x 20.5mm
• 3 antenna options: Integrated ceramic antenna, Hirose U.FL coaxial connector or single port 50Ω pad

• Wide supply voltage (2.8 to 3.6V)
• Current consumption below 2uA in deep sleep mode with self wakeup
• Module ships with AT-style software interface based on the mesh stack of EmberZNet 2.xx.
• 12 general-purpose I/O lines and 2 analogue inputs (all 17 GPIOs of EM250 are accessible)
• Supports 4 different power modes for extended battery life
• Firmware upgrades via RS232 or over the air (password protected)
• Hardware supported encryption (AES-128)
• CE and FCC compliance with integrated antenna plus a selection of external antenna, FCC modular approval
• Operating temperature range: -40°C to +85°C
• Can act as an End Device, Router or Coordinator
• Future Options: On board, low power voltage regulator, DC/DC regulator and watch crystal
• Optional board-to-board or board-to-cable connector

Radio Features

• Based on the Ember EM250 single chip ZigBee / IEEE802.15.4 solution
• 2.4GHz ISM Band
• 250kbit/s over the air data rate - NB actual usable data throughput with ZigBee is 20kbps
• 16 channels (802.15.4 Channel 11 to 26)
• +18dBm output power (<100mA)
• High sensitivity of -97dBm typ. At 1% packet error rate
• Hardware acceleration for IEEE 802.15.4 compliant transmissions

Example AT-Style Commands

AT+EN Establish PAN network

AT+BCAST Sends a Broadcast

AT+UCAST: Sends a Unicast

AT+JN Join PAN

At Power up the last configuration is loaded from S-registers. This can eliminate the need for a host controller.
