Digi XBee-PRO® DigiMesh® RF modules provide costeffective wireless connectivity to electronic devices. They are interoperable with other DigiMesh feature set devices, including devices from other vendors. Digi XBee-PRO DigiMesh modules are ideal for applications in the energy and controls markets where manufacturing efficiencies are critical.
The Serial Peripheral Interface (SPI) provides a highspeed interface and optimizes integration with embedded microcontrollers, lowering development costs and reducing time to market. Digi’s DigiMesh compatible module is based on the Ember EM35x (EM357 and EM3587) system on chip (SoC) radio ICs from Silicon Labs, utilizing 32-bit ARM® Cortex® M3 processor.
