"For the Internet of things, the popular understanding is to connect devices to the cloud. How to connect to the cloud? At present, the main technologies are WiFi, 2G / 3G / 4G and Nb IOT. Among them, WiFi plays a particularly prominent role. It is not too much to say that it is the mainstay, which mainly depends on factors such as price, market application maturity and so on. However, as a communication technology in the generalized Internet of things, in addition to the connection to the cloud in the last step, there are also communication modes such as local interconnection and networking, such as ble, ZigBee, sub GHz, Lora, etc. An excellent Internet of things product design, in addition to considering its own functions, how to achieve high-quality network connection is particularly important. It is even said that many Internet of things devices need to rely on the combination of various networks to maximize the advantages of the product.
At present, there are countless boards related to the Internet of things on the market, which adds a lot of trouble to the selection of engineers. Therefore, in this issue, aiban.com will recommend 16 carefully selected Internet of things development boards with their own characteristics for your reference.
