2.4G wireless usb dongle


The 2.4G wireless USB Dongle features a JN516x wireless microcontroller and allows communication with this JN516x device from a USB connection. The JN516x device can act as a node of a wireless network. Thus, the dongle provides an easy way of interfacing a host machine (such as a PC) to a wireless network based on the IEEE802.15.4, JenNet-IP, ZigBee PRO (ZigBee Light Link or Smart Energy) or ZigBee-RF4CE networking protocol. An FTDI device provides the USB connection between the host machine and the JN516x device, which in turn provides the radio interface to the wireless network.

It has the following features:

  1. USB 2.0 Full-Speed Compatible Interface
  2. IEEE 802.15.4-based wireless microcontroller (JN516x) with the following radio characteristics:
  3. ŸTransmit Power: 2.5 dBm (typ.)
  4. ŸTransmit Current: 15mA (typ.)
  5. ŸReceive Sensitivity: –95dBm (typ.)
  6. ŸReceive Current: 17.5mA (typ.)
  7. Integrated printed RF antenna
  8. General-purpose LEDs
  9. Serial Flash memory device (4 Mbits)
  10. 32-kHz crystal oscillator

Typical uses of the dongle include:

  1. A complete and stable hardware environment for the development of IEEE802.15.4, JenNet-IP, ZigBee PRO (ZigBee Light Link or Smart Energy) and ZigBee-RF4CE networking applications, facilitating an accelerated time-to-market for wireless network products
  2. The basis of a packet sniffer for IEEE 802.15.4-based wireless communications
  3. A means of integrating the host machine into a wireless network, typically as the network Co-ordinator

The mcu of the dongle --JN516x wireless microcontrollers-- share a number of common features and benefits, including:

  1. Ultra-low power, high-performance MCU together with an IEEE802.15.4-compliant 2.4GHz radio transceiver
  2. Enhanced 32-bit RISC processor offering high coding efficiency through variable-width instructions, a multi-stage instruction pipeline, and low-power operation with programmable clock speeds and various sleep modes
  3. On-chip Flash memory for non-volatile storage of application, networking stack and software libraries
  4. On-chip RAM and EEPROM, allowing the device to run a wireless networking stack together with an embedded application, or to run in a co-processor mode
  5. A rich mix of analogue and digital peripherals
  6. Low-current solution for long battery-life, allowing operation directly from a coin cell
