The USB-KW24D512 development platform includes the following Features:
• Freescale’s low-power MKW24D512 SIP ZigBee™ platform
• Fully compliant IEEE 802.15.4 Standard 2006 transceiver supports 250 kbps O-QPSK data in 5.0
MHz channels and full spread-spectrum encode and decode.
• USB form factor for reference design and small footprint, low cost RF node
— Differential input/output port used with external balun for single port operation
— Low external component count
— Programmable output power from –32 dBm to +8 dBm feed to the Antenna
— Receiver sensitivity: –101 dBm, typical (@1% PER for 20 byte payload packet) feed to the
antenna
• Integrated PCB Folded F-type antenna
• 32 MHz reference oscillator
• 2.4 GHz frequency operation (ISM)
• Programmable frequency clock output (CLK_OUT)
• Full speed USB 2.0
• Cortex 10-pin (0.05”) JTAG debug port for target MCU
• 2 blue LED indicators
• 1 push button switch
• 1 Reset push button
