CEL MeshConnect™ EM357 Mini Transceiver Modules

CEL's MeshConnect ™ EM357 Mini Transceiver Modules combine a high performance RF solution with the premier ZigBee® stack on the market. This single chip solution consists of an RF transceiver with the baseband modem, a hardwired MAC and an embedded 32-bit ARM® Cortex™-M3 microcontroller with internal RAM (12kB) and Flash (192kB) memory. Available in low and high power options (+8dBm and +20dBm), these modules can accommodate variable range and performance requirements. The tiny module footprint makes them suitable for a wide range of ZigBee applications. CEL's MeshConnect EM357 Mini Modules are based on the Ember EM357 ZigBee compliant system-on-chip (SoC) radio IC.
