HCS12 Board Design Complete!

This is the finished design of my semester 4 project in college.

The task is to design and build a board to control DC motors, servos, stepper motors, and read motor encoders all to drive a robot (that will be next semester’s project)

Here’s the PCB layout:

Pretty neat, eh?

What this board includes:

• Accelerometer
• DC motor driver
• Stepper motor driver
• Servo driver
• Input for motor encoders
• Serial Communication interface via RS-232 (and can be manually swapped to a bluetooth module)
• LCD Display

The board will be powered by a 12V supply and has 5VD, 5VA and 3.3VD supplies built in

The next step is to get the board manufactured and populated with components!
