Hardware Overview - EL Escudo Dos
This section will cover the unique features of the EL Escudo Dos Arduino Shield.
Shield Headers
These headers allow the shield to be connected to any Arduino Uno/Uno R3 compatible board. We will be using the SparkFun RedBoard for this example.
Currently, the EL Escudo Dos Shield is designed for the original Arduino Uno footprint (not the R3 footprint). However, this shield can be used with Arduino Uno R3 boards without issue.
Channel Headers
The EL Escudo also provides a row of 0.1" spaced headers to allow the user to read the signals from the microcontroller to the EL wires. This is beneficial for debugging.
