 The 24LC32 EE Prom breakout. This is some memory that you can write information to and it's not gonna go away when you pull the power on it. So what I'm gonna do is I'll go ahead and plug in one of my EE Prom breakouts and nothing fancy I'll just reset the board and now when it restarts you'll see it loaded in the first four bytes of information on the EE Prom. So it looked at address 0, 1, 2, and 3 and from that it grabbed these hex values. So what others? Those are the RGB values of a number of neopixels. So now what I can do is go ahead and unplug that just like a game cartridge. Plug in a different one and again I'll just go ahead and reset and now we've loaded in some different values right off of for the chip there. That's the product pick of the week. It is the 24LC32 EE Prom breakout on I2C Stem-A-Q-T Form Factor.
