The CC3000 WiFi Shield is a highly practical Arduino shield featuring the CC3000 WiFi chipset developed by Texas Instruments.
Unlike similar modules, it uses the SPI interface instead of UART, allowing you to send data at your desired speed. With its IRQ pin, it supports asynchronous operation. It is compatible with 802.11b/g wireless networks, supports open/WEP/WPA/WPA2 security, and TKIP & AES encryption. It can operate as both client and server for TCP and UDP communication. Note: it does not support AP mode, meaning it can connect to access points but cannot act as one.
The CC3000 module includes a unique SmartConfig feature. With SmartConfig, you don’t need to manually enter a new network’s ID and password in your Arduino code each time you connect. Using the official iOS, Android, or PC app released by Texas Instruments, you can directly configure the network parameters (SSID, password, etc.) on the CC3000 module.
The shield comes with a built-in WiFi antenna and also provides a standard uFL connector for an external antenna, allowing use in enclosed cases or situations requiring antenna extension without signal loss.
It also includes a micro SD card slot, enabling storage of files needed for network operations on an SD card. You can use Arduino’s SD library for SD card operations. The SD card SS pin is pin 4.
Features:
- Compatible with Arduino Uno
- Interface: SPI @ 16MHz
- TCP speed: ~4 Mbps
- Supports IEEE 802.11 b/g networks
- Security modes: WEP, WPA/WPA2 (AES & TKIP - Personal)
- FCC, IC, CE, and TELEC certified
- Built-in ceramic antenna and external antenna support
Note: When using the CC3000 Shield, it is recommended to power the Arduino with an external 1A adapter, as USB power alone may cause instability or lockups.
Compatibility: The CC3000 Shield is fully compatible with the Adafruit-designed shield, so you can refer to Adafruit libraries and schematics.
