Article: Selecting the Right Components

This article is all about Hardware Component Selection. How to Begin and parameters to look at.

Step 1: List the major components required

Prepare a list containing broad descriptions of components required. For eg:- A typical list could contain the following: Controller, RS232 Driver, Voltage Regulator , High Speed RAM , Flash Memory, USB connector, OPAMPs, LCD etc.

Step 2: List the features required for each Component

For each of the components in list above prepare a list of features required for that component based on the requirements of the project. For the RS232 Driver the features could be Speed - 9.6 Kbps, Number of pairs - 2, Operating Voltage - 3.3V, Isolation 1500V, Package - SOIC and so on.

Step 3: Comparison of different makes

Compare 3 - 5 components against the feature table above. Select the best match. If two or more match the feature list, look at extra features which may be useful in the long run.
