Product Descriptions

The EWM32M-xxxT20S series (UART) is an ultra small, low-cost wireless serial port module (UART) that uses LORA communication technology that is fully compatible and interoperable with E32. Its transmission power is 20dBm, and it has multiple transmission modes. It operates in the 433 frequency band and 900 frequency band, with TTL level output and can also accommodate 3.3V IO port voltage.

EWM32M-xxxT20S has the advantages of longer communication distance, strong anti-interference ability, and extremely strong confidentiality. The default air speed at the factory is 2.4kbps and the transmission power is 20dBm, which improves communication stability and extends communication distance; The two modules in the following figure have the same power but different frequency bands.

Product Features

• Adopting the new generation LoRa spread spectrum modulation technology, it brings longer communication distance and stronger anti-interference ability;

• Support serial port firmware upgrade, making firmware updates more convenient;

• Supports AT commands, making it more convenient to use;

• Support FEC forward error correction to improve communication stability;

• Support global license free ISM 433MHz frequency band or 868/915MHz EU common frequency band;

• Support users to set their own communication keys, which cannot be read, greatly improving the confidentiality of user data;

• Support LBT function, listen to channel environment noise before sending, which can greatly improve the communication success rate of the module in harsh environments;

• Support wireless parameter configuration, remotely configure or read wireless module parameters by sending command packets wirelessly;

• Support air wake-up, which is an ultra-low power consumption function, suitable for battery powered application solutions;

• Support fixed-point transmission, broadcast transmission, and channel monitoring;

• Supports deep sleep mode, with a power consumption of approximately 3uA for the entire machine;

• Under ideal conditions, the communication distance can reach 5km;

• Save parameters after power failure, and the module will work according to the set parameters after power on again;

• Efficient watchdog design, once an exception occurs, the module will automatically restart and continue to work according to the previous parameter settings;

• Supports data transmission rates ranging from 2.4K to 19.2Kbps;

• Supports 2.7-5.5V power supply, with optimal performance guaranteed for power supplies greater than 5V;

• Industrial standard design, supporting long-term use at -40~+85 ℃;

• The maximum module power can reach 100mW (20dBm), with longer and more stable transmission.
