EE192: Mechatronics Design LabCheckpoint 4: PCB Schematic and layoutIn preparation for printed circuit design, turn in complete schematic for all electronics you want on your PCB. This includes motor driver, and DC-DC buck converter (or linear regulator). Include values, and part numbers. Also include connectors (marked clearly!), and mounting holes as needed for standoffs or heatsinks. You might have a battery cable wired to this board, or motors as well. These would need mounting holes for large gauge wire as well. It is recomended that copper traces not be added yet until you get feedback on schematic. Note: You do NOT need to show me the design/layout (placement of components and routing of traces) for this checkpoint. The finalized layout is due Tuesday Feb 20 at 11:59 pm on Bcourses. In disussion (Wed Feb 21 and Thurs Feb 22) you will peer review each others pcbs. You then have time to make any needed changes before the final Gerbers are due (Friday Feb 23 at 3:59pm on Bcourses). Checkpoint 4: motor from batteryThis checkpoint is largely a simple extension of the previous one, except the motor must be powered from the battery. Like checkpoint 2, this is so you can dedicate time to finishing and iterating on your circuit boards designs. Checkoff ProcedureYour motor should be properly attached to the chassis and must drive the wheels. Motor power must come from the battery and control signals must be generated by your microcontroller board running your code (single program). You may use the serial terminal to send manual control signals (like setting the motor duty cycle). You may continue to power the microcontroller board from the USB port as you won't have your DC/DC converters yet. You will be quizzed to demonstrate how to use the battery. All power connection must be soldered properly. Your hardware should not be damaged (i.e. components should not catch fire) during any of these tests. Demonstrate your motor driver circuit works and is safe running from your battery (in any order, instructor's choice): Brushed motor (Using 11.1 LiPo battery)
