LoRa intelligent networking chip

ZSL420/ZSL421/ZSL860/ZSL861

ZSL420/ZSL421/ZSL860/ZSL861 are four LoRa intelligent networking chips, and support various modulation modes such as LoRa, FSK and GFSK. Combined with spectrum broadening processing technology, the long-distance communication problem of small data in a complex environment is solved. The operating frequency of ZSL420/ZSL421 is 470MHZ~510MHz, and the operating frequency of ZSL860/ZSL861 is 863MHZ~870MHz. They support the transparent transmission protocol for embedded ad hoc network and one-click networking, and provide LinkWAN protocol, CLAA protocol and LoRaWAN protocol (only ZSL420/ZSL421). The chip has a built-in open 32-bit Arm^® Cortex^®-M0+ core, a basic frequency of 48MHz, 256 KB Flash, and 32KB SRAM, which is convenient for users to redevelop the functions. It is an excellent choice in the wireless communication field of IoT.
