Setting Up the TWR-34933EVB with an External Signal Resource
The following procedure describes how to set up the hardware when the TWR-34933EVB is used with no MCU board connected.
1. Connect the load to connectors J7 (Motor 2A & Motor 2B) and J6 (Motor 1A & Motor 1B).
2. Connect the 2.0 V to 7.0 V DC power supply to connector J8 (motor power supply) and a 3.3 V DC power supply to connect J38
(digital power supply).
3. Connect signal generator to IN1A/IN1B & IN2A/IN2B with the PWM signal.
4. Turn on the power supply and signal generator and evaluate the performance.
Figure 9 illustrates the procedure.

Setting Up the TWR-34933EVB with the Tower Platform
When configured as a Tower platform module, the TWR-34933EVB must be used in conjunction with another Tower MCU evaluation board
(available at http://www.freescale.com/tower). The following procedure describes how to set up the hardware when the TWR-34933EVB
is used with the TWR-KV10Z32 board, as an example:
1. Assemble the Tower platform by sliding the TWR-34933EVB elevator connectors into the top slots on the Tower Elevator modules.
Insert the Tower MCU evaluation board in the Tower Elevator modules in a set of slots below the TWR-34933EVB.
2. Connect the USB cable between the PC and the USB port on the Tower MCU evaluation board.
3. Connect the load to connectors J7 (Motor 2A & Motor 2B) and J6 (Motor 1A & Motor 1B) on the TWR-34933EVB.
4. Connect the 2.0 V to 7.0 V DC power supply to connector J8 (motor power supply) on the evaluation board.
5. Launch the software application used to communicate with the board (for example, Processor Expert).
Figure 10 illustrates the procedure.

Setting up the TWR-34933EVB with the Freedom Platform
The TWR-34933EVB is compatible with Freescale’s Freedom Platform. When used in this configuration, the TWR-34933EVB must
interface with the Freedom EVB (available at http://www.freescale.com/freedom). The TWR-34933EVB should not be used with other
Tower modules when connected to a Freedom board.
The following procedure describes how to set up the hardware when the TWR-34933EVB is used with the FRDM-KL25Z board, as an
example:
1. Connect the load to connectors J7 (Motor 2A & Motor 2B) and J6 (Motor 1A & Motor 1B) on the TWR-34933EVB evaluation board.
2. Insert the Arduino™ R3 header connectors into connector J1/J2 and J9/J10 on the evaluation board.
3. Mount the FRDM-KL25Z board to the Arduino™ connectors on the evaluation board.
4. Connect the 2.0 V to 7.0 V DC power supply to connector J8 (motor power supply) on the evaluation board.
5. Insert the Mini-B plug of the USB cable into the USB port labelled USBKL25Z on the FRDM-KL25Z board.
6. Insert the standard A plug of the USB cable into the PC.
7. Launch the software application used to communicate with the board (for example, Processor Expert).
Figure 11 illustrates the procedure.
