The 4809 is the brain of the EZA Board. Using the EZA Board you are unlikely to damage the 4809 (far less likely than when wiring to an Arduino by hand). It is socketed for your convenience, so you can easily swap it out in the rare case you damage it.

In the frequently asked questions portion of the book I share some tips on how to avoid damaging the 4809.

Install with the text right-way up (the small half-circle notch will be facing left).

(I’ll let you in on a secret: Depending on availability your EZA Board might already come with a complimentary 4809 replacement chip. I’d hate for you to have to be interrupted for several days if your chip gets damaged…)
