Hello all,
I have a question for everyone here I recently purchased a sparkfun protoshield from my local micro
Center and it didn’t come with instructions on how to wire sensors to it. I don’t want to use a breadboard
I want to make the connections perminant. The shield is all soldered together but I can’t for the life of me
Figure out how to wire a adxl345, itg3200, and a hmc5883l to the shield. The shield will be going on a mega2560 R3.
Are all the through holes connected to each other?
Only the 5V and GND bus'es are connected together (but, obviously, not to each other). The rest of the through holes in the proto area are just like every other proto-board, not connected. You put your ICs on the top side and do point to point wiring & soldering on the back side. Though I suppose any placement (top or bottom) that works for you is OK.Tim Tim:

Perhaps this will help :
Thank’s for the reply! that was the exact answer I was looking for.
Would you happen to know where I could get some info on how to
Get the sensors talking to each other?
Interface them to the MCU first.
Hello Leon! Thanks for the reply! But if you don’t mind me asking
How exactly would interface them? If you could point me in the right
Direction for a decent tutorial that would be perfect.
Sorry, I’ve never used any of those sensors. You will have to go through the documentation, wire them up and write the software. Have you done this sort of thing before? If not, you are in for a lot of work.
I believe all the sensors are I2C so the OP will need to learn all about that. The datasheets will also tell him what external components, like caps and resistors and such, are needed. A look at the SF schematics for the BoB’s that use the same sensors would be a good idea. One problem that needs attention right up from is that all the sensors are 3.3V parts while the Mega is a 5V device. And I don’t know if (??) the protoshield brings 3.3V up to it. So the OP will need to find a way to power the sensors and make sure the interfaces work with the mixed voltage.
