Following on from Part 3, our motor controller has been successfully built and tested, now it’s time to release the parts used, where to place them, etc so you can build your own. I’ve actually taken consideration to what I said in Part 3 and have re-designed the Motor Controller to have the components and lines to be spaced out a bit more however I’ve changed the lines back to 0.254mm wide. You have the option of both v1.0 or v1.1 boards, I recommend v1.1 even though it is a little bigger.
Now it’s time for the part that you and I have been waiting for, the PCB development of this circuit! It sure did take me while to get everything I need for this and a some research on this topic but in the end it all worked out. This is a step by step guide to how to develop your PCB using a collaboration of various resources I’ve found on the net so you should be set to make your own PCB once you have a design after reading this.
Following on from Part 1, we’ve done our design and now it’s to put our prototype to the test, this will post won’t be as long as the design because all we need to do is test.
This is how our circuit looks to power 1 motor in 1 direction only.
So here we are, we’re going to build us a motor controller to control 2 motors in both directions. First we’ll start off with our design which shows how our components will be connected and our reasoning, we could of just bought a motor controller chip like the L298N but we will rather learn something from our build and it should be easier to use than the L298N chip. Another on the plus our motor controller will have is about 1/2 the Vce of the L298N which is an advantage when dealing with low voltage motors and low voltage power supplies as well as back EMF protection (both will be explained).
This is quite a long post and do remember that I’m also new to understanding all of these concepts so do feel free to correct me if I’m doing something wrong! I’ve spent a good month checking all this out, posting on an electronics forum and trying to grasp the concepts I’ll be explaining you.
AdvanceVGA – Play your GBA on the big screen! Swap out the LCD for our board, solder some wires, connect 5V USB and VGA and you’re ready to go.
GBxCart RW allows you to backup GB/GBC/GBA ROMs, save or restore game saves and re-write supported flash carts. Mini RW option available for GB/GBC only.
Wireless Gameboy Controller – Use your Gameboy, mGB, GBC, GBA, GBA SP, GB Micro, NDS and NDS Lite as a wireless controller on Windows, Linux, Raspberry Pi, etc, and on your NES, SNES, N64, Gamecube and Wii.
