This is a breakout board for the CC3000 WiFi Module. The CC3000 from Texas Instruments is a self-contained 802.11b/g wireless network processor that makes incorporating internet connectivity into your project simple. Instead of the more standard UART communication method, the CC3000 module utilizes a SPI interface allowing you to control the flow of data as you please. What makes the CC3000 unique is its ability to associate to a WiFi access point using a cell phone app in the Texas Instruments process called SmartConfig.
This board also provides an optional feature that allows you to attach an external antenna, just in case you need a little extra power. This is useful if you want to route an antenna to the outside of an enclosure or to increase your WiFi gain. The board has a U.FL connector for this purpose. You will have to move the Antenna Select capacitor if you want to use an external antenna.
You can use this board with any microcontroller that communicates via SPI using 3.3V or 5V logic. Note however that the CC3000 does not share the SPI bus with other devices. You can add a tri-state buffer like 74AHC1G125 to the MISO line to fix this issue.
CC3000 Module Board Pinout
- GND should be connected to the host circuit's ground.
- VCC is the supply voltage and should receive 4.3V to 15V (only if you are unable to provide 3.3V to the 3.3V pin).
- 3.3V should be connected to a 3.3V power source if one is available. Use this pin or VCC — never both.
- MOSI should be connected to the SPI MOSI pin of the host microcontroller.
- MISO should be connected to the SPI MISO pin of the host microcontroller.
- CS should be connected to a SPI chip select pin of the host microcontroller.
- INT should be connected to a pin capable of external interrupts on the host microcontroller.
- SCK should be connected to the SPI clock line of the host microcontroller.
- EN should be connected to any GPIO pin on the host microcontroller.
