1. Overview
1.1 Brief introduction
E19-433M30S is 1W SMD wireless module working at 433MHz,
developed based on chip SX1278 from Semtech.
Due to the use of the imported SX1278 as the core of the module,
with PA and LNA its sens itivity and stability are largely improved when
tx power is 1W.Compared with the FSK、GFSK products, it has made
great progres s in receiving current, receiving sensitivity, transmitting
power, receiving rate range and anti-interference ability. The module is
aimed at smart home, wireless meter reading, scientific research and
medical, and medium and long distance wireless communication
equipment. Since RF performance and component selection are in accordance with indus trial standards, and the product
has obtained FCC, CE, RoHS and other international authoritative certification reports, users do not need to worry about
its performance. High precision 32MHz crys tal is used.
Since the module is a pure RF trans ceiver module, you need to use the MCU driver or a dedicated SPI debug tool.
1.2 Features
Communication distance tested is up to 10km
Maximum trans mission power of 1W, software multi-level adjus table；
Support the global license-free ISM 833MH band；
Support air date rate of 0.018kbps~37.5kbps in LoRaTM；
The maximu m data trans mission rate 300kpbs in FSK mode；
Support multiple modulation methods , LoRaTM/FSK/GFSK/MSK/GMSK/OOK；
Large capacity FIFO, supports 256Byte data buffer；
Support 2.5V~5.5V power supply, power supply over 5.0V can guarantee the best performance；
Industrial grade standard design, support -40 ~ 85 °C for working over a long time；
Stamp hole, good for secondary development and integration.
1.3 Application
Home security alarm and remote keyless entry；
Smart home and indus trial sensors ；
Wireless alarm security system；
Building automation solutions ；
Wireless industrial-grade remote control；
Health care products；
Advanced Meter Reading Architecture(AMI)；
Automotive indus try applications.
