5554 is an EMS under development based on the the 32 bit 132 MHz Freescale MPC5554 processor. The FreeScale MPC5554 processor wil give it all the connections or features you could probably ever want, but will be use a DIY assembled Input/Output board so you only need to purchase and install the components you actually need. This design will allow 5554 to be assembled for as little as $750 for a basic application and under $1000 with all features installed while out performing commercial ECUs costing 10 times more.

The aim of your resume is to provide a reference for your claims against the selection criteria. Selection Advisory Committees will cross check the claims you have made in your selection criteria with the information you have provided in your resume writer, to assess the validity of your claims. These two documents combined will win you an interview so that you have the opportunity to impress the employer in person.
