Hi!
We’ve finished our prototype using an Arduino UNO and a Roving Networks RV-XV for connectivity.
We are ready to have our design built onto a custom circuit board, but the issue is that our code is almost exactly 32K in size, and we were thinking of giving ourselves more room just in case. Also, it wouldn’t hurt if things ran a little faster.
So, I was wondering if anyone had advice for us. If you needed to move up in storage and/or possibly speed, what would the next best step up from an ATMEGA328 be?
We will only be manufacturing about 3,000 boards a year so I was thinking about even jumping up to the new Arm Cortex based chip they are using for the Due, but it might not be possible due to other hardware engineering concerns (I’m a software guy)
But there is the 640, the 1280, the 2560, and so on. Any advice is appreciated. Thanks!
