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.

Key Features

  • TI CC1310 Wireless MCU with dual-core architecture: 48MHz Cortex-M3 for application and Cortex-M0 for RF processing.
  • Long-range 900MHz UHF transceiver with configurable output power (4-14 dBm) and high receiver sensitivity (-108 dBm).
  • Flexible air data rate selection from 2.5 kbps to 168 kbps to optimize for range, data throughput, or power consumption.
  • Integrated memory includes 128KB of Flash and 20KB of SRAM for on-device firmware and wireless stack.
  • Simple serial integration via UART (TTL) interface with a 2048-byte data buffer for reliable packet handling.
  • Compact and embeddable SMD design measuring 14mm x 20mm, suitable for high-volume PCB assembly.
  • Dual antenna interface options: IPEX connector for external antenna or PCB stamp holes for a printed antenna.
  • Low-power wireless operation ideal for battery-powered remote sensor nodes and telemetry units.

Applications

  • Industrial wireless sensor networks for telemetry and IIoT monitoring.
  • Long-range environmental sensing systems (soil moisture, weather stations).
  • Asset tracking and fleet management solutions in warehouses or large facilities.
  • Smart agriculture applications for crop monitoring and irrigation control.
  • Wireless data links for remote control and automation in sub-urban areas.

Frequently Asked Questions

How do I communicate with the E70-900T14S module from my microcontroller?

Connect the module's UART TX and RX pins to your MCU's corresponding RX and TX pins at 3.3V logic levels. Power the module with a stable 2.1V to 3.6V supply. Use simple serial AT-style commands (format depends on pre-loaded firmware) sent at the configured baud rate (e.g., 9600 or 115200) to control transmission, reception, and RF parameter settings. Always ensure common ground between devices.

What is the power consumption during transmission and reception?

Current draw varies with configured RF output power. At maximum 14 dBm output, expect a peak transmit current in the range of tens of milliamps. During active reception, the current is typically lower, in the range of 10-20 mA. The module supports low-power sleep modes managed via the CC1310's internal power management controller, which can reduce current to microamps when the radio and MCU are idle, crucial for battery operation.

Can I develop custom firmware directly on the CC1310 MCU?

Yes, the module's CC1310F128RSM chip provides 128KB Flash and 20KB RAM for your application code. You can develop using Texas Instruments' Code Composer Studio or the Arduino core for CC13xx. You'll need a compatible JTAG/SWD debugger (like an XDS110) to program the chip via its debug pins. This allows you to implement custom protocols, sensor drivers, and power-saving routines directly on the module, eliminating an external MCU.

What antenna should I use, and how do I connect it?

Use a 900MHz antenna with 50-ohm impedance. For the IPEX connector version, attach a compatible IPEX-to-SMA pigtail cable. For the stamp hole version, design a quarter-wave monopole or meandered trace antenna directly on your PCB. Proper antenna matching is critical for range; consider using a matching network if designing a custom PCB antenna. Keep the RF trace short and avoid running it near noisy digital signals or power lines.
