1.Overview

1.1 Introduction

E70-433T14S2 wireless transceiver modules, operating at

425~450.5MHz (Default: 433MHz), is based on originally imported

CC1310(build-in dual core ARM) from TI, with TTL level output,

3.3V IO port voltage,24MHz industrial high-precision low-

temperature drift crystal vibration; Ensure its industrial ability and

stability.

The module features FEC (Forward Error Correction)

algorithm, which ensure its high coding efficiency & good

correction performance. In the case of sudden interference, it can

correct the interfered data packets proactively, so that the reliability

& transmission range are improved correspondingly. But without FEC, those data packets can only be dropped.

With built-in low power multifunctional wireless serial program, users can also conduct secondary development.

Accordingly.

1.2 Features

 Communication distance tested is up to 1.5km  Maximum transmission power of 25mW, software multi-level adjustable；  Super low receiving current of 8mA;  Small size: 14x20mm;  Support RSSI;  Development based on CC1310, with dual core ARM;  Support the global license-free ISM 433MHz band；  Support air date rate of 2.5kbps～168kbps；  Low power consumption for battery supplied applications；  Can achieve up to 115200bps continuous frame unlimited-packet length transmission;  Support 2.2V~3.8V power supply, power supply over 3.3V can guarantee the best performance；  Industrial grade standard design, support -40 ~ 85 °C for working over a long time；  IPEX access point, stamp hole is optional, Facilitate user secondary development, facilitate integration.

1.3 Application

 Home security alarm and remote keyless entry；  Smart home and industrial sensors；  Wireless alarm security system；  Building automation solutions；  Wireless industrial-grade remote control；  Health care products；  Advanced Meter Reading Architecture(AMI)；  Automotive industry applications.
