So, I recently purchased a Atmega 328 online. I am still waiting for it in the mail,. and I am wondering what the difference between the one in the photo (the one I ordered) and the Arduino boards such as the Uno, that you can get that use the Atmega 328 board. Does it have the same capabilities? What are its limits compared to the Uno/other boards??
It looks like the big difference is that your board doesn't have USB. It's designed to use an external "FTDI cable", rather than having the USB/Serial conversion built-in.
It has extra A7 and A8 (see your photo).
The board linked to is not one of them.
