Next Step: Breadboard

A project log for GBAA: Game Boy Advance Arduino

An Arduino- based prototyping handheld housed in a GBA case

While I wait for my screens and stuff to arrive I'm going to stick my three microcontrollers onto a breadboard and start trying to get them communicating and playing nicely.

I was tempted to try and shoehorn them straight into the case, but I want to see where the screen fits in. If it sits deep in the case I won't be able to fit my boards behind it (which is a bit of a bummer), but I have a backup plan.

I'm thinking of putting the pro micro behind the screen (with the micro usb port sticking out of the link cable hole), and fit the other two in the battery compartment. Rather than using AA/AAA batteries I'm going to use a LiPo, but I'm sure that can fit somewhere else :-)

I really have to give a thumbs up for breadboarding first, many boards have been ordered - I should have breadboarded them first :D Good luck with the project!

Ha ha, cheers mate!

I definitely think if I knew how to use KiCad I would be an order-first-test-later bloke ha ha.

Breadboarding in this instance is easy; it's only i2c and power that need linking in together for now. It could get a bit more messy when I start trying to test the nano's pins as slaves to the Pro Micro ha ha!

My KiCad efforts so far: I've made one board! It's the tiniest and simplest breakout board for an I2S microphone, where I have no Idea how to use it  ... (yet) ... I should make an ESP12 footprint next (or google one) - but all in all I was surprised that I went through with it.

I just stumbled over the pro trinket keypad and saw the massive I2C updates inspired by your input :) good luck with the breadboarding :)

I need to learn how to design boards as my ability to bodge, fix and make suck. I have some great ideas, but don't have the skill to bring them to life.; if I can design boards and use pre-existing enclosures I may just have half a chance :-)

I do love my i2c ha ha. A lot of my ideas are modular, and i2c is just ideal for easily tying those modules together.

similar here... I bought a bunch of old/useless electronic gizmos in quantities for cheap just for their cases, then design boards to fit in 'em. (Helps when you've got a lot of the same cases, so the layout's reusable). Can be done with solderable-protoboard, too, though.

@esot.eric That's why I've gone for the GBA case for this one :-) It only cost me £3, and I've got a few project ideas that rotate around this kind of form factor.

Once I've got the components doing as they should I'll be using some protoboard to assemble my first interation; easy to solder components and connections to is, and also easy to cut up to fit my case.
