1.2 Jumper Settings and Test Points
Figure 3. Board Jumpers and Test Points
The jumper settings and test points are as follows:
micro-USB (J1) — Use J1 to interface to a micro-USB cable used to download a program to the
MSP430™ MCU memory and run it.
GP Push Button or MCU Reset (J2) — Set J2 to RESET for MCU reset functionality or PUSH for
general-purpose input functionality.
Spy-Bi-Wire (J3) — J3 is for a serialized JTAG protocol used for MSP430 MCUs. J3 can connect an
MSP430 Spy-Bi-Wire male header to this female header. It can be used to program the MSP430™
MCU on the EVM instead of using the USB-to-JTAG interfaces.
Test and Interface Header (J4) — J4 can be used to monitor input or output signals from the EVM or
supply external control signals.
Power Phase Test Pinouts — These pinouts are used to measure the single H-bridge node voltages.
To Motor — Two-port bulk header to connect the brushed DC motor.
To Power Supply — Two-port power-supply bulk header. This header accepts supplies from 5.9 V to
45 V.
