You can solder parts to the prototyping area to create your project, or use it with a Tiny breadboard to quickly test circuit ideas without having to solder. It's got extra connections for all of the Arduino I/O pins, and it's got space to mount through-hole and surface mount integrated circuits. It's a convenient way to make your custom circuit and Arduino into a single module. **Specifications** - It can be overlayed on the Sunfounder Mega2560 board directly. A Tiny breadboard is provided, which you can use to do some simple experiments. - Provide a footprint for SOP28. - It's got extra connections for all of the Arduino I/O pins - We offer you pin22-pin53 bonding pad and you can use it to weld the component directly.
