Robotis - ZIG-110A Set
The Zig110A Set includes a pair of Zigbee modules (Zig100/Zig110) to add Zigbee Wireless Connectivity to your Robot.
This is small sized communications module with built-in MCU and Zigbee IC inside. The modules establish a PAN (Personal Area Network) to implement transparent UART communication on the 2.4 GHz frequency.
Compared to Bluetooth (BT-110A), Zigbee offers
somewhat improved reliability in environments where the 2.4Ghz frequency is very noisy.
On the other hand, Zigbee modules need the special Zig2Serial interface to connect to the PC where the BT-110A can connect directly to any Bluetooth enabled Laptop or PC.
A Zig-110A module is usually included with all Bioloid PREMUM and Bioloid GP Robots. Zigbee is the default Wireless Technology on Robotis products.
