4.2.4 Power Measurement
It is possible to isolate various circuit blocks to measure current draw via 0-ohm resistors. The resistors
are all mounted as default.
Below is a list of the supply nodes.
• R8 -> V_RS232 (Supply for RS-232 Transceiver circuit)
• R6 -> V_PERIF (Output from on-board regulator for GPIO customer access)
• R5 -> V_LCD (Supply for LCD Daughter Board)
• R21 -> V_BB (Supply for QE128 EVB)
• R20 -> V_RF (Supply for MC1320x)
• R3 -> V_LED (Supply for LEDs)
• R2 -> VCC (Output from main on-board regulator)
4.3 MC9S08QE128 MCU Module
The MC9S08QE128 MCU is provided as a module that mounts as a daughter card on the main PBC. Four
2x8 headers designated J7, J8, J10, and J11 are used to mount the module.
NOTE
The MCU is mounted to the module during manufacturing. Freescale
recommends that users do not remove and replace this module.
4.4 RF Circuitry
The 1320x-QE128EVB RF circuitry contains a printed metal F-antenna (ANT1).
4.5 USB Connector (“B” Receptacle)
The USB connector is a “B”-type device and is designated as J12. Figure 4-2 shows the connector pinout.
The USB port is connected to MCU port SCI2.

4.6 LCD Connector
The LCD module is connected to the main circuit board via one of two 16-pin connectors (either J16 or
J17). Each connector supports a different LCD module format. The default LCD designated as the
CFAH1602B device uses the J17 connector.
