Did you know, that if you took out all your blood vessels and laid them end-to-end,

…you would probably die? Because really, that’s something you shouldn’t be doing.

Luckily, this isn’t the case with an altimeter! We can lay out the electrical circuit without affecting the operation of the altimeter into a prototyping board, as you can see in the photo above.

Believe it or not, the prototype above is actually testing a number of things:

  • power circuits
  • low-battery indicator
  • HDR ambient-light sensor
  • firmware programming and and checking available memory
  • I2C communication with the MEMS sensor chip
  • microcontroller clock frequency
  • altimeter self-test procedures

Now that we’ve verified these features, we then package it up into Tritium, ready for more testing!
