The BlackWidow is an Arduino Duemilanove compatible clone that has 802.11b wireless connectivity baked directly onto the board. The components have been switched out for surface mount equivalents to free up space for the wireless module. It is fully compatible with the Processing/Wiring IDE. The BlackWidow will give your Arduino projects added wireless connectivity without the need for additional bulky shields!
: For WiFi usage, a minimum of 5 digital pins are required: 4 for SPI and 1 for interrupt. The interrupt is switchable between digital pin 8 and digital pin 2. The SPI bus can be shared with other SPI devices, but the CS pin cannot be modified from pin 10. Your other SPI device must have a switchable SPI CS pin, or a hardware modification needs to be performed.
