The AsyncLabs Black Widow 1.0 is an Arduino Duemilanove clone with 802.11b wireless onboard. The USB-B connector has been replaced by a USB-mini-B connector (on the other end of the board!) and the WiFi module has taken it's place. The power supply connector is also changed to a 2-pin JST connector to save space.
802.11b has a maximum speed of 11Mbps, but because of overhead, maximum TCP throughput is around 5.9Mbps. This is not fast for WiFi, but is much faster than you can expect to maintain with an ATmega328.
