EYSGJNAWY-WX application field and working principle

　　EYSGJNAWY-WX is a short range radio transceiver module, used to realize half-duplex wireless communication between two microcontrollers. It adopts GFSK modulation technology，with the features of low power consumption, long communication distance, and strong anti-interference. This module can be widely used in home automation, industrial control, wireless POS, security monitoring system, anti-theft alarm, etc.　　The EYSGJNAWY-WX module is composed of three parts: RF transceiver, high performance 8-bit C51 microcontroller and several peripheral resources. As a global leading RF chips manufacturer, STMicroelectronics supplies the transceiver chip used in the module. This chip supports a wide input voltage range，from 1.8V to 3.6V, and integrates PA and LNA inside to realize a long connection distance and low power consumption. The higher integration also brings a smaller size, up to only 20.2mm×20.2mm.　　The internal 8-bit 51 microcontroller with 256K FLASH is customized for this module, and has built-in efficient UART, I2C, SPI multi-channel operating protocol to connect the end devices. This technical design enables a faster data rate, higher penetration, and better anti-interference. The EYSGJNAWY-WX module also includes other rich peripheral resources: supporting various serial port settings, hardware flow control, 300bps to 115200bps, CRC check, checksum and other features; supporting multiple hardware reset and wake up methods; supporting software update technology. 　　Technically, after different mechanisms are triggered for power on, the module will enter the safe mode automatically. The execution of program will wait for instructions from the host controller. After receiving the instructions, the module will realize the transceiver function, the communication distance can be up to 500 meters in open areas. All commands are under the control of the host controller, which can be a Bluetooth function source, displaying data, and performing other operations.　　Integrating RF signal source, modem, and interface module, EYSGJNAWY-WX module makes full use of the mobile media transmission and forwarding, providing a high-performance data transmission solution. This RF transceiver module has strong scalability, wide applicable field, and rich application, so it is widely applied in many types of home appliance, medical equipment, security devices, controllers, and industrial equipment.
