Description
The E70-900T14S is a professional-grade sub-1GHz RF transceiver module designed for long-range, low-power IoT sensor networks and wireless telemetry systems. At its core is the Texas Instruments CC1310 wireless MCU, which pairs a 48MHz ARM Cortex-M3 processor for application code with a dedicated Cortex-M0 core to handle all RF protocol tasks. This architecture ensures stable wireless performance while freeing the main MCU for sensor data processing and power management.
The module operates in the 900MHz UHF band, offering superior penetration and range compared to 2.4GHz solutions. Its RF front-end is configurable, delivering transmit power from 4 dBm to 14 dBm to optimize for either extended range or lower power consumption. Coupled with a high sensitivity receiver (-108 dBm), it achieves robust communication links over distances up to 1500 meters in open areas. The integrated 128KB Flash and 20KB RAM provide ample space for custom firmware development directly on the module.
Integration is streamlined via a simple UART (TTL) serial interface, allowing developers to send and receive data packets without deep RF expertise. The module’s 2048-byte buffer handles data bursts efficiently. Its compact SMD footprint and dual antenna options (IPEX connector or PCB stamp hole) make it ideal for embedding into industrial sensors, agricultural monitors, asset trackers, and smart utility meters requiring reliable, mid-range wireless connectivity.
