A lot of the specific panels in the ProtoSnap LilyPad developing Board are not at all hard; they have one component that is big and possibly a couple of tiny supporting elements, like resistors.
- 5 Digital I/O pins
- 4 Analog pins
- Integrated LED on pin 13
- Integrated ON/OFF switch
- Built-in energy supply socket (JST connector) for the 3.7V LiPo battery and asking circuit ( no extra battery pack charger required)
- Simplified design with less pins, providing more room for sewing or less projects that are complex
Central into the Simple board may be the ATmega328 — the top black colored square in the midst of the board.
Here is the microprocessor, the “brains associated with the procedure.” This is just what shops and executes your Arduino design. Surrounding the ATmega328 are some passive supporting elements, absolutely absolutely nothing all that important to you personally.
