GETTING STARTED
3.1.1
Overview
The BDC add-on (DM164130-6) allows you to drive virtually most brushed DC motors
used in consumer electronics. The add-on is shipped together with the NMB brushed
DC motor (PAN14EE12AA1) mounted on the board. The motor voltage is supplied
through jumper J5. Alternatively, any other 5-12V BDC motor can be used by hooking
it up through the J4 connector and removing the shorting block from J5.

Features
The key features of this board include the following:
Connectors:
• Male 20-pin connector (J1) to match the F1 LV Evaluation Platform
• Generic 4-pin BLDC motor connector (J4) for 22 AWG wire
• 5-12V power supply input connector (J3)
Typical BDC drive:
• Two N-type and two P-type MOSFETs arranged as an H-bridge
• Four NPN bipolar transistors to command the MOSFETs
• Sensing resistor for current measurement (R15)
Control:
• V
