UART/SPI WiFi Module

The IoT era involves all kinds of fields and industries, such as the intelligent hardware for consumers' market, as well as agriculture and transportation in the industrial field. This all-embracing model has determined that the market be fragmented, where software is used to differentiate. That's when middleware emerged, to reduce the developing cycle of common features, and to meet the market needs of trend standardization, hardware diversification and application liberalization.

  • Stable exquisite production processAll modules have been mass production, the production stage of the layers of checks and will be tested in the factory to ensure the normal use of the customer.
  • Perfect product documentation systemHas accumulated more than 200 product support documents, each model of the module from the hardware design, software development, application tools, application notes, and other angles to improve.
  • Professional and timely technical supportRAK’s technical support team provides online support throughout the day, providing professional and comprehensive solutions for the problems encountered by developers.
  • Rigorous testing of multiple directionsRAK modules have been authoritative testing agencies strict testing, as many as 10 test report can guarantee the performance of the module and the data is accurate.

Support of SSL/GMMP/MQTT

  • ☼ Support SSL encryption mode, ensuring all communication data being encrypted, secure and stable.
  • ☼ The general transmission protocol MQTT of the IoT industry is supported, and the data volume and the occupation of cyber resources are small.
  • ☼ Support the local communication protocol GMMP (customization needed)

Securely One Step

  • ☼ Quickly join the network through the one-key configuration equipment of mobile phone APP, allowing more "no screen" devices to connect the network and realizing the IoT;
  • ☼ As an internet accessing method, Easy config is simple and convenient to use, only needing to install the corresponding APP in the smart terminal devices and enter the password. Compared with similar products, the success rate is higher, and the compatibility is better.

Real Low Power Consumption

  • ☼ OFF(Standby): <~1.1uA
  • ☼ Idle & WIFI associated:3mA
  • ☼ Tx/Rx Avg.::~10mA(100B/100ms)
