I’m playing with a new wifi module today from WizNet, the WizFi210. I have mine mounted on a test board that has 9 pin rs-232, usb, and TTL Serial interfaces. There is an Arduino shield available as well. This is a inexpensive wifi board that can be used for many applications, from smart appliances to wireless sensor monitoring. For ease of testing and prototyping, the test board or the shield are a necessity.
The wifi module itself is the square board on the right end of the test board, covered in metal, with the antenna attached. There is a version with on board chip antenna as well. I’ll be documenting the setup and Arduino sketches necessary for communicating with this device, as well as it’s applicability to working with a Raspberry Pi. Stay tuned!
