1323x Remote Extender Motherboard
5.1 1323x-REM Overview
The 1323x-Remote Extender Motherboard (1323x-REM) is a motherboard that accepts the
1323x-Modular Reference Board (1323x-MRB) plug-in module (daughtercard) and supplies a power
supply and set of interface peripherals. The two boards in combination provide a simple platform to
evaluate the MC1323x, develop software, and demonstrate IEEE 802.15.4 based networking capabilities.
5.1.1 Features
The 1323x-REM provides the following features:
• Small form factor (3.1 x 3.1 inches)
• 2-Layer metal, 0.034 inch thick FR4 board
• Two connectors provide daughter card mounting
— 20-Pin primary connector
— 18-Pin secondary connector
— Provide main supply voltage to board
— Provide access to all MC13233 GPIO
• Flexible power supply
— Sources include USB port, two AA batteries, or DC source
— Power-On LED
—On-Off switch
• USB <> UART serial port
• 2x4 Switch matrix
• IR receiver
• Four application controlled blue indicator LEDs
• Secondary set of pin headers uses jumpers to enable/disable IO connections and allows user
application connection to MC13233 GPIO
