E64-DTU (433NW20) - Wireless Data Transmitter

E64-DTU (433NW20) - Wireless Data Transmitter

Module E64-DTU (433NW20) is suitable for low-power star networks with one master and multiple slave devices. Its main advantage is support for data transmission from up to 31 slave devices simultaneously to the master device, and support for WOR (Wake-on-Radio) mode in slave modules, where the power consumption during reception in this mode is only approx. 3 mA.

Reliability and data correctness is ensured by strict data verification and automatic retransmission mechanism between the master and slave devices.

Module E64-DTU (433NW20) supports master and slave device mode:

• In master device mode the module listens and receives data from multiple slave devices.

• In slave device mode either WOR mode (allowing activation by transmission from the master device) or transmission mode (where the slave itself sends data to the master device) can be set.

The maximum transmit power of the module is 100 mW, operates in the 425 to 451.3 MHz band and uses command transmission mode. The module communicates with the user MCU via UART interface, operating voltage is in the range 8V to 28V.

Functions and features:

• All key components are originally imported – higher performance, smaller dimensions, lower costs
• Maximum transmit power 100 mW, technical parameters comply with European industrial standards
• Temperature compensation for frequency stability better than ±1.5PPM
• Operating temperature: -40℃ to +85℃, suitable even for extreme environments, fully industrial design
• Compact aluminum housing with excellent heat dissipation, EMI shielding and high resistance to interference
• Protection against reverse polarity, overload and antenna overvoltage – higher reliability
• Configurable parameters: power, channel, speed, address etc.
• Ultra low power consumption: standby current only 14 mA (less in power saving and sleep modes), transmit current ≤ 130 mA
• Integrated watchdog and precise timing – automatic restart on error while preserving settings
• Uses original SEMTECH SX1278 chip, very reliable and popular among users
