Description

Design a small PCB (ideally 100mm X 100mm or smaller) capable of accurately measuring the vehicle's, linear acceleration, angular velocity, linear velocity and other mechanical states. It should also output the measured data over the bike's CAN network. The board should be compatible with the bike’s 12V0 supply.

User Guide - IMU V0

Functional Description / User Guide

This is a document that captures an overview of each subsystem, use case, and relevant components. Similar to a User Guide, this document explains how to use a feature of a project. For example, it will explain the necessary hardware connections and how to communicate over CAN to the BMS. There may be several Function Descriptions (one for each revision).

IMU Testing

Test Plan

This is a spreadsheet of each test that confirms that the project satisfies each engineering requirement.

Fallacies and Pitfalls

soldering

<Example: We did not use the correct resistor values for our power indicator diodes. We resolved this issue by carefully writing out the Ohm's Law equations, and used Digikey's calculator.>

Revision Changes

Electrical projects may go through 2-3 revisions before the project is complete. Keep a record of changes for each revision. I recommend following the outline below:

Revision 2:

Recalculated resistor value for LED1, now the LED1 lights up when the board is powered up.
Found the correct measurement chip footprint and fixed it in Altium.

Revision 1:

Base project, ordered from PCBway and discovered that the measurement chip footprint was inverted. Also, the 3.3V LED1 would not light up.
