Greetings,

Please add better comparison charts and consistent features lists.

For example, I am trying to compare the Pro Micro and the Teensy 3.0. The Teensy has a much longer list of features. Is that because it has more features or because features are missing from the Pro Micro list?

For example, the Teensy list "128K Flash Memory, 16K RAM, 2K EEPROM", and the Pro Micro does not list any memory. Does it have memory? If so, what kind and how much?

Thanks

You are comparing bicycles to a BMW. These are 2 different classes of microcontrollers. If you need more details of an item, read the datasheet and/or manual. Sparkfun is here to help you, not hold your hand.

Yes with the help of combination charts and comparision charts it becomes easy to list out the various features, as charts helps us in a proper visualization.
