The JZX905 embedded GPRS module is a product that relies on China Mobile's GPRS network platform to achieve wireless data communication. It overcomes the shortcomings of traditional wireless communication methods, such as short communication distance and unstable performance, and provides users with a virtual dedicated data communication network that is high-speed, always online, and transparent for data transmission. Truly achieving seamless coverage without distance limitations, enabling nationwide roaming. Widely used in industries such as power automation, industrial monitoring, traffic management, meteorology, finance, environmental monitoring, coal mining, oil fields, securities, etc. Utilizing the GPRS network platform to achieve transparent transmission of data, while considering the networking needs of various application departments, it has great flexibility in the form of network formation.

Product Features
Ultra low power consumption, with a current of less than 6uA during sleep mode; ER26500 is powered by batteries and communicates once every 2 weeks, which theoretically can last for more than 10 years
● Supports chip SIM cards without the need for a SIM card holder, avoiding poor contact or oxidation that may affect SIM card reading and writing
● Ultra low voltage operation: When the voltage of the lithium battery drops to 2.8V (the battery is usually dead at 2.6V), the module can still work normally
● Independently developed, embedded 32-bit ARMV7 MCU with real-time operating system
The working frequency adopts 850/900/1800/1900MHz, and the four frequencies can be applied to all countries around the world (including North and South America)
The module works in HTTP UDP mode to save power consumption and has a timed automatic wake-up function. The wake-up cycle can be customized by the user
The module supports photoelectric direct reading of tables, 188 protocol, 645 protocol, and remote valve opening and closing
Embedded watchdog, wide power management, no crashes, automatic recovery when disconnected, multiple working modes to choose from, flexible and convenient
Anti interference design, even in the event of hardware deadlock and ordinary watchdog unable to serve the processor and communication module, it can still reliably and automatically restore to normal state
● Standard Industrial TTL
● Equipment operation indication and network connection display
● Provide user settings software and open interfaces
Industrial embedded design, easy installation, working temperature: -25 ℃ -75 ℃, communication is not affected at -25 ℃
