ZigBee USB Dongle
- Products Status:Used
The USB connector on device is standard USB Type A. This allows connection to the power and serial data connection from USB host.
USB interface device
The USB interface device is an FTDI FD232RL device. It is used to interface between the data connections of the USB port and the standard UART connection for UART0 of the JN5148 device.
With the FTDI royalty-free drivers, the USB dongle will appear as a COM port on a Windows PC. Therefore, for many applications there is no requirement to develop USB drivers. For detail of installing the device driver, refer to the JN51xx Flash Programmer User Guide (JN-UG-3007).
The power for the dongle is sourced from the USB connector. The wireless microcontroller cannot be directly connected to the USB port. The USB interface device generates the required voltage levels for the JN5148 and the design provides all the necessary decoupling of these supplies.
The wireless microcontroller on the dongle board is the NXP (Jennic) JN5148, which is detailed in the JN5148 Data Sheet (JN-DS-JN5148). To facilitate the development of JN5148 wireless network applications on a PC, Jennic provide the JN5148 Software Developer’s Kit (SDK). This SDK includes Application Programming Interfaces (APIs) and development tools, and is supplied as two installers: SDK libraries (JN-SW-4040) and SDK Toolchain (JN-SW-4041).
There are a RED LED and Blue LED on the device.
Red LED can be controlled by the JN5148 wireless microcontroller DIO16;
Blue LED can be controlled by DIO17. The pin is driven low, the LED is illuminated.
There is a push button that can be controlled by the JN5148 wireless microcontroller DIO9. It is low active.
The LED and switch is the same position.
