Seeeduino Board Comparison

Although this is a very basic question, I could not find it in the product wikis or by searching the forums. I need to compare the differences between the various Seeeduino boards, particularly between the Seeeduino V2.1 and the Seeeduino mega. Could someone point me to a link? Thank you.

At our home page you can see a search bar on the right with a blue “Search” button.Such as you search “Seeeduino” then you can see various about Seeeduino board or others are on display.Same with WIKI.

Thank you, yuriq.
