SPI WiFi Module With Microchip MRF24WB0MA

Introduction :

Getting you Arduino into WiFi network is not a fresh news any more. We introduced our UART WiFi Module which easily gets your Arduino into WiFi.

But now Users who use UART WiFi Module will find that the operation is very easy, and programming is pretty easy, too. Basically once you configured it well, you don't need to do further configuring work in the future until the wifi network changes. Each time while it is powered up, it accesses to the wifi network automatically. However, the data speed may not satisfy your needs. Because the data go through UART, and UART speed is limited.

Well, this new Arduino WiFi Module sends and receives data through SPI interface. The max data speed is 2Mbps. Basically you can transmit picture or vedio wirelessly. Also, this new shield supports AES encryption, more safer while transmitting your data. This shield requires much programming code.

So here is the difference :
 

Feature :

1、Compatible with Arduino UNO, Mega, Duemilanove and so on

2、Compatible with most none-Arduino platform with SPI such as PIC

3、Power: 5V DC

4、Interface: SPI

5、Plug and play solution

6、Compatible with Arduino UNO, Diecimila, Duemilanove and Mega series

7、IEEE Std. 802.11b/g/n compatible

8、Data Rate: 1 and 2 Mbps

9、Uses SPI for host communication (max speed 25MHz)

10、Easy access reset button on-board

11、Solder-switchable interrupt pin usage between INT0 and digital pin 8

12、16 Mbit on-board DataFlash, can be used to store webpages, sensor logs, etc.

13、Extra port to facilitate usage for non-Arduino platform such as PIC.

14、Supports 802.1x, 802.1i security: WEP, WPA-PSK, and WPA-2-PSK.

15、Hardware Security Engine for AES and RC4-based ciphers

16、Support AdHoc.

Description :

WiFi access to the LAN is already a common way. We have introduced a wired way to access LAN. Is it possible for Arduino to access LAN via WiFi? The answer is yes. We are here to introduce a WiFi wireless communication module based on SPI.

To use this module, first we need to start with https://github.com/asynclabs/WiShield to download the appropriate library, or you can download our testing version. The library files should be extracted to the Arduino (we tested using the Arduino-0021) libraries directory, and rename it to WiFi and restart Arduino IDE.

In order to communicate with access point (AP) or wireless router (Router), this WiFi module needs to be configured, including the wireless network ID (SSID) and encryption methods. At present, the WiFi module can support WEP, WPA / TKIP-PSK and WPA2/AES-PSK encryption. Before configuring WiFi module, you need to understand clearly your AP or router's configuration. Here we used a NETGEAR wireless router, with WPA encryption. Configuration as shown below :
