The ultra-low power design is applied at system level, in the different 3GPP modes of operation. WNB301H supports various interfaces such as UART, I2C, SPI* and so on. The module provides customer high flexibility for different kind of applications. Due to the compact form factor, ultra-low power consumption and good performance, WNB301H is the best choice to be embedded to the design or solution for SmartX applications, ex. smart cities, smart metering and grid, security and asset tracking, environmental monitoring and control, health care monitoring, etc.<\/p>\n<h2>Document:<\/h2>\n<p>PDF\u00a0download<\/p>\n<h2>General Description:<\/h2>\n<div class=\"page\" title=\"Page 7\">\n<div class=\"section\">\n<div class=\"layoutArea\">\n<div class=\"column\">\n<p>WNB303R is an SMD type module with LCC package, with an ultra-compact profile of 18.0mm \u00d7 16.0.0mm \u00d7 2.35mm, which can be easily embedded into applications. It provides hardware interfaces such as ADC, GPIO, and UART interfaces, and can meet almost all the requirements for IoT applications, such as smart metering, bike sharing, smart parking, smart city, security and asset tracking, home appliances, agricultural and environmental monitoring, etc.<\/p>\n<p>Designed with power saving technique, the WNB303R consumes an ultra-low current of Typ. 3.3uA in PSM (Power Saving Mode). The module fully complies with the RoHS directive of the European Union.<\/p>\n<p>WNB303R provides protocol stacks (UDP\/TCP, CoAP, NIDD, Http(s)&#8230;etc.) and also supports LWM2M\/MQTT cloud platform as below, which provide great convenience for customers&#8217;
