# Hardware

The Silicon Spike device is composed by:

·       Arduino Uno R4 Minima  (product details here:[ https://store.arduino.cc/products/uno-r4-minima](https://store.arduino.cc/products/uno-r4-minima) );

·       Three BNC pins;

·       One LED and its proper resistor;

·       One USB type-C;

·       One 9 Volt 2.1mm power jack

These components need to be assembled following this scheme:

Eventually, you can use a female BNC instead of a male one, according to your necessities. Also, you can use the LED color you prefer – and, consequently, the proper resistance. Importantly, in order to grant both data transmission and the square digital wave on the recording, you need to plug the motherboard with both USB-C and 9 Volt 2.1mm power jack.

&#x20;        Once soldered and assembled the above components the device will work properly. However, we suggest building a case (Fig. 2) for the device, in order to avoid any potential damage which might hamper its functioning.
