Some days ago I posted about my first homebrew DIY breakout board for the ADXL345 accelerometer. That was pretty ugly but worked very good.
Today, after some other tests, I show you my new homebrew DIY breakout board: this time it is for an ITG3200 gyroscope. And you’ll see that I really improved a lot!
Some changes between the previous breakout board:
- I’m now using an FR4 board instead of a bekelite one. Bakelite is easy to drill and really light weight but it can’t handle the reflow process temperature: it burns. FR4 instead is really better: after the reflow it doesn’t have any signs of damage.
- I’m now using smd capacitors instead of through hole. This helps keeping the size of the board small.
- The board has now two sides: top and bottom. This also helps keeping the size small and making everything more polished.
In the attachment you find the kicad sources, the printer ready PDF, and the Arduino and Processing programs. The processing programs need to be executed on the Processing IDE, available for download from http://processing.org/
Remember to adjust the serial port configuration in the Processing code to match your connection to the Arduino in your system. Here I use /dev/ttyUSB9, if you are under windows you’ll probably have to use something like COM3 or something like that. See in the Arduino IDE under Tools->Serial Port to get the exact value you have to use.
In the next days I will create some more breakout boards for the ADXL345 and the HMC5843 ICs. Stay tuned!
