All that I hoped for

This is exactly what I was looking for in a development board. I am developing a new product and using the Pi Compute is perfect for the application. This development board provides all the flexibility I need and the features I was going to have to breadboard to interface with. For example the SD card reader and the USB ports.


I'm a software engineer who is interested in hardware, but have had a tough time getting inspired to do more than what I found in guidebooks that came with my arduino. Keep that in mind since my review is likely going to be surface level as compared to the level of critique more seasoned enthusiasts may be able to offer. I bought this as part of a dev kit bundle that came with a ton of accessories, but this product seems to be of great quality, they expose every port imaginable to you so that you can flash an image, run some code, and get off the ground fast focusing on what you want your CM3 to do. They provide some tutorials in the datasheet for beginners like myself to get more familiar, and this pretty much brings the CM3 to a level of accessibility as the Pi B+. Even if you can find other IO boards on the market, this one is a really good bet.
