Accelerometer Basics

March 28, 2013

A quick introduction to accelerometers, how they work, and why they're used.
  • Thank you for the feedback! We’ll definitely take a look at that the next time this board is up for revision.

  • If you run the command “Show VRAW”, it will highlight all traces labeled VRAW in the schematic. This tool works for any signal/part you’d like to trace out on the board and schematic. Regarding HV_AREF, it is labeled to differentiate it from AREF on the Teensy.

  • VRAW connects to the input on the 5V regulator. We didn’t include all the possible power configurations for the AREF and IOREF pins simply to keep costs down. It’d be up to the user to connect those to the proper power supply for their particular project/shield they are using.

  • Do you mean a shield adapter for Pro Minis? That’s great feedback - thanks!

  • They simply didn’t sell well enough and we couldn’t keep the manufacturing price low enough to keep them on the storefront. Also, this clears out space for other new and fun products!

  • First guess is there’s something weird going on with your power supply system. Are you powering the shield and the inverter from the same 12V? Do you have a common ground between your bare conductive board and the Escudo? There also is the possibility that it could be an issue with the tape/wire you are using. Try switching the order that the wires are connected on the board and see if the issue follows a particular wire or if it stays on a certain pin on the Escudo. That will help narrow down where to check for issues.

  • Get back in touch with tech support. If they already received your other board back, they might have a better idea as to what went wrong with the set up and give you some pointers as to what could be the culprit.

  • I think what you are seeing are the locking header footprint that we use to keep the headers stable in the selective solder machine. The headers are actually on straight.

  • It did get fixed, the files just didn’t get updated. It looks like our autonotify for the pcb swap didn’t trigger correctly for us to update the files. Those should be updated momentarily. Sorry about that!

  • There are different interpreters out there such as this one. A quick search for “GCODE Arduino” has a lot of results (hurray for the expansion of 3D printers!).
