Project Summary

The goal of this project is to create a carrier board for an L298 H-Bridge with 1000mf cap, 12 diodes, a terminal block for power and two motors, and a header for interfacing with a microcontroller. The board is based on a simple L298 H-Bridge design by Clay Timmons.

Note that the board can be made using just the bottom artwork. The top artwork is informational only and contains text explaining diode orientation and pinouts.
