Well, in most cases you won’t need a breadboard and the reason for that is the way the Tinusaur Board has been designed with 2 2-row headers that give you enough pins to do some prototyping directly on the board.
The 2 outer rows are always GND while the 2 inner rows are always signal (except when they duplicate the GND), and the Vcc is inner as well. On the newer version of the board, there is also e separate 2-pin (female or male) external power connector. The board could be powered by a coin cell battery as well or directly through the USBasp programmer. So, with 18+2=20 pins in total, it is more like a tiny breadboard where you can stick some wires or even some parts. Pretty neat, isn’t it?
If you’re not ready yet to prototype your own circuit you can use some of the shields we’ve got. To learn how to make a LED blink you could use the Tinusaur Shield LEDx2 or the upcoming Tinusaur Shield LEDx3. For more advanced topics you could use the Tinusaur Shield EDUx4IO that can help you learn how to work with buttons, produce sounds with a buzzer, read analog data such as light intensity using a photoresistor, and many other things.
So the answer is NO, you won’t need a breadboard in most cases.
