This is our most popular XBee wireless module: the series 1 802.15.4 protocol 1mW with wire antenna. Its good for point-to-point, multipoint and convertible to a mesh network point. We suggest this module for those starting out as it is the easiest to get going.
The core module HC-06 main modules, leads the interface includes VCC, GND, TXD, RXD, KEY pin high trigger to clear the pairing information re search led indicate Bluetooth connection status, flash unpaired slow flash indicates paired but not slave connection, Always follow machine connected
This 4" / 100mm long flexible uFL 2.4GHz antenna has approx 4DBi gain and a 50Ω impedance so it will work fantastically with just about any 2.4-2.5GHz wireless receiver/transmitter such as the Adafruit CC3000s!
Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE UART Friend!
Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well.
This serial WiFi transceiver module is based on ESP8266 SoC.. ESP8266 is a highly integrated chip that has Integrated TCP/IP protocol stack. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
