Hardware

The Silicon Spike device is composed by:

· Arduino Uno R4 Minima (product details here: 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:

Silicon Spike’s hardware in a.) its schematic circuit, and b.) graphical representation.

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.

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.

A few examples of how the circuit can be arranged into a case.
