PCB Design

Software: Eagle CAD

Motor Control Board

Task

Needed to create a home made stepper motor control board to integrate with current system. Reduced COGS of system and increased flexibility. Also easier to debug problems.

  • Contains 2 DRV8825 stepper driver with encoder feedback capability

  • Able to detect signal from an optical homing sensor in each axis

Sensor Chip Reader Board

Task

Footprint of the original multichannel reader needs to be decreased in order to fit inside Proteus Robotics System

  • Able to read 16 channels(samples) from 1 assay

  • Compact footprint to fit on Proteus Robotic System

Main Control Board

Task

Needed to create a main control board that diminished the number of serial communication wires for the final product
