ETRX3 ZigBee Module features the EM357 and EM351the latest ARM Cortex M-3 SOCs from Ember. The modules have a footprint of just 19 × 25 mm for both standard and PA/LNA versions. They are available with either an on-board antennae or a Hirose U.FL connector to allow connection of external antennae. A link budget of 105 dB on the standard ETRX3 module gives excellent performance, and RF power can be further boosted by use of the ETRX3-LR, which adds an extra LNA+PA, boosting the link budget to 123 dB. The ETRX3 series are low power 2.4 GHz ZigBee modules integrating a 2.4 GHz, IEEE 802.15.4 compliant transceiver with up to 192 k of flash, 12 k of RAM, and many advanced peripherals.
