Air302 Module Nb-iot Development Board Full Netcom Nbiot Wireless Communication Multi-band Compatible With Gprs

Description: The Air302 module is an ultra-low-cost, ultra-low-power NB-IOT module that supports the 3GPP Rel14 NB-IOT standard. The working frequency band of Air302 is: B1 B3 B5 B8. Air302 has an ultra-small size of 17.7mm x 14.8mm x 2.3mm, which can almost meet all M2M needs. Air302 has a built-in 32Mb Nor Flash + 2Mb SRAM, and supports Hezhou's unique Luat open source platform, which is convenient for customers to do secondary development and greatly reduces the development cycle and cost of customers. Air302 has a wealth of peripheral interfaces, supports UART, SPI, I2C and other interfaces, can support up to 19 GPIO, and supports ADC to meet the requirements of various application scenarios. Air302 is a SMD module, which is packaged in LCC and can be embedded in customer applications through its pin pads, providing a rich hardware interface between the module and the customer's motherboard. The Air302 module uses power saving technology, and the current consumption is as low as 800nA in PSM mode. Air302 has built-in protocols such as TCP, UDP, PPP, HTTPS, and SSL, and the embedded extended AT commands can make it easier for users to use these Internet protocols. Air302 module is fully RoHS compliant.
