System Overview and Functional Descriptions Augmenting the core device on the Sensor Node are: • Low-cost 2.4 GHz ISM Band radio • 2.0 USB connection • User interface LED • Optional debug / development port • Reset switch Users are encouraged to reference the board schematic for the topics covered in the following sections. Figure 3-4 and Figure 3-5 shows the 1322x USB Dongle/Zniffer PCB top and bottom view with interface designations.
System Overview and Functional Descriptions 3.4 Low-cost 2.4 GHz ISM Band radio The MC1322x provides an onboard balun, antenna switch, and LNA. The only external component required for the radio is an antenna. The USB dongle uses a PCB-mounted chip antenna. Figure 3-6 shows the RF network external to the MC1322x. • Typical nominal output power is 0 dBm, with +4 dBm max • Typical sensitivity is -95 dBm.
System Overview and Functional Descriptions 3.6 Clock The MC1322x device has a primary reference oscillator of 24 MHz. Crystal X1 is used with the MC1322x for the reference oscillator. 3.7 Reset Switch and LEDs The USB dongle provides the following • One green Power-On LED (D5) • One red LED (D1) is driven by the MCU and controlled by the software application. • Reset switch to the wireless node; does not reset the USB interface device. Table 3-1.
System Overview and Functional Descriptions 5. Disconnect the USB board from USB port. 6. Remove the jumpers from both J3 and J4. 7. The board is now ready for boot operation. After the FLASH is erased, plug the module into the USB connection again. The board is now ready to be loaded with a new image using the Freescale Test Tool application. NOTE Refer to the Freescale Test Tool User’s Guide as supplied with Test Tool in the BeeKit Wireless Connectivity Toolkit download.
