PCB Assembly Services - Screaming Circuits: Building boards for the Intel Edison


Building boards for the Intel Edison

I've recently spent some time getting familiar with the Intel Edison. The Edison has a dual-core 500 MHZ Intel Atom processor, with built-in Wi-Fi and Bluetooth. It comes with 1GB of RAM, 4GB of eMMC internal storage, and a USB 2.0 OTG controller. It doesn't bring any of the connectors (power or signal) out in a usable form. Rather, it's designed to be plugged onto another board through a 70-pin high density connector from Hirose.

I designed a small board with I2C (both 5 volt and 3 volt connectors) and a micro-SD card slot. My board still doesn't have the power or console connectors. For that, I'm using a base board from Sparkfun.

Step one of the assembly process, is, of course, to design and layout the board. Using the Sparkfun open source designs as a jumping off point, I ended up with the nice, compact layout (1.2" x 1.75") shown below.

After getting the files ready and placing a turn-key order on our website, I followed the board through with my camera. Here it is after offline setup, with the parts ready for robot pick and place.

I abbreviated the process a bit, but those are the major process steps along the way.

Great article, my website is a professional manufacturer of wiring harness, I hope everyone can visit my website, https://www.wiringo.com

The very good project about Building Boards for the Intel Edison. I learned a lot.

Brilliant tutorial on building boards for the Intel Edison! Let me share this because My followers should read this article. Thanks

Great article. I am going to share with my students.
