An introduction to selected official Arduino boards
The list of official Arduino boards is long and growing. At this point, you know what the significant differences between the boards are and what to look for when you select an Arduino board for your next robot project. Feel free to put your new knowledge to the test and see if you can narrow down your choice for a board that meets your requirements the best from the list of Arduino boards here: https://store-usa.arduino.cc/collections/boards.
Let us also look at two direct alternatives to the Arduino Uno that you are likely to want to consider at some point: the Arduino Nano and the Arduino Mega 2560.
