Product Description
RF-SM-1077B2 Ultra-Low-Power 433 MHz & 470 MHz Wireless Module for Home Automation
RF-SM-1077B2 Sub-1 GHz module is based on TI CC1310, which combines a flexible, very low-power RF transceiver with a powerful 48 MHz ARM? Cortex?-M3 microcontroller supporting multiple physical layers and RF standards and a dedicated radio controller Cortex?-M0 handling RF protocol commands that are stored in ROM or RAM. RF-SM-1077B2 integrates a 24.0 MHz crystal, a balun, a band pass filter, an antenna matching and an IPEX antenna matching which make the module low cost, low power consumption and long wireless communication in Sub-1 GHz.
