I need a H-Bridge part #3

My two last posts about this subject were rather general. I have since then ordered some equipment, and spent a lot of time thinking about how to build my motor control board. This post will summarize what I have pondered thus far.

• I will first build a working circuit of the power part (H-Bridge) of the motor control board  using a breadboard. I will play around with it, and switch components and wiring until i can get it to work optimally. I will use my RB-100 controller to drive it.
• Once I am satisfied with the power part, I will continue with the control part. In this stage I will use the RB-100 to send commands to the control part over I2C or similar, and create software on the receiving end using a PIC controller on board the control board that in turn will drive the power board.
• Once the whole configuration has been thoroughly tested and works flawlessly under all sorts of extreme conditions such as motor stalls/ over-power/under-power/ forced reversal, extreme temperatures, and once I get optimal power efficiency, I will continue by making a compact set of PCB layouts, and continue with etching them and building the first version.

For the power part, I have gathered a set of information resources that I think is really good. Here is a list of links:

• General tricks for PCB layout.
• A comprehensive lot of in-depth quality information about building a performance H-Bridge (H-Bridge secrets). Part2 and part3.
• Beginner introduction to H-Bridge construction.
• A collection of implemented H-Bridge designs with notes.
• Step by step implementation of a H-Bridge design with component specs and prices.
