The wifiBUG provides a complete 2.4 GHz IEEE 802.11 wireless LAN module, which is based around the incredibly popular RN171 module. It can be configured using simple ASCII commands and provides a complete TCP/IP networking stack supporting TCP, UDP, DHCP, DNS, ICMP, ARP, HTTP client and FTP client abilities. Onboard LEDs provide status feedback and the RN171 sensor and IO pins are available (if required) through the wifiBUGs 8 and 10 way headers.
This is a half size stickyBUG and occupies one half of a stickySHIELD. This means you can have two half size bugs per shield or you can have one half size BUG and two quarter size BUGs per shield. They can be stacked on other stickySHIELDs if required. Only one wifiBUG should be used for any given design.
This shield uses RS232 communication on the Tx2 and Rx2 pins. The nature of simple RS232 communication means that it is not recommended you use another stickyBUG that shares RS232 communication on pins Tx2 and Rx2.
