Yet another WiFi click today — WiFi3. This one carries the ES8266 module which received a lot of hype last year since it was featured on Hackaday. Back then you couldn’t get a non-chinese data sheet for it. Today it landed on a click board.
The ESP8266 module with a system on a chip will completely offload all networking functions from the MCU. It has a, you could say mandatory, integrated TCP/IP stack, but more than that, the SoC has powerful processing and storage capabilities for a WiFi module.
In addition to a standard mikroBUS socket, WiFi3 click also has 6 additional GPIO pins you can use to connect and control external electronics.
We’re giving you all these WiFi options (this being our fourth click board with a WiFi module) because that’s the most obvious, maybe easiest way to connect your devices to the web. There’s a WiFi router with an internet connection in every home or office more or less. We don’t want to push it, but the fact is, you gotta have a WiFi module in your click board collection if you want venture into IoT.
