I’m looking for some help. I need the good schematic for SD slot and connection with imp. I’m tryed with Spark Fun schematic and have problems to prototype my project. To working needs a pull up in card detected? It’s so confused.
Here is some general information about building hardware for the imp.
And here is a list of open reference designs we’ve made for the imp.
All of the designs include schematics, BOMs, and gerber files. Feel free to use them as is, learn from them, and modify them to your heart’s content!
@mandark …and you need the ATSHA204 IC. Without this the imp won’t appear in your planner.
