+# Controlador PWM: Diseño de Placa Base y Gabinete
+
+Introduccion al Diseño Asistido por Computadora (86.70) - FIUBA
+Martin Klöckner - [mklockner@fi.uba.ar](mailto:mklockner@fi.uba.ar)
+
+## Introducción
+
+En el presente trabajo se diseña la placa base y el gabinete de un controlador
+modulado por ancho de pulsos (Controlador PWM en adelante). Para el diseño de
+ambos componentes se utilizan programas de computadora, en particular KiCAD para
+el diseño y simulacion de la placa base y FreeCAD para el diseño del gabinete y
+de componentes del circuito cuyo modelo 3D no se incluyen en la librería
+estandár de KiCAD.
+
+La idea original del controlador pertence al usuario Creative Creator del
+sitio web [hackster.io](hackster.io).[^1]

+
+## Diseño de Placa Base
+
+En la figura 1 a continuacion se muestra el esquematico completo dibujado en
+KiCAD siguiendo el diseño mencionado en la introducción, además se agrega una
+fuente de alimentacion de 12 volts, junto con un LED y una resistencia como
+carga, esto para simular el circuito, como se muestra en la directiva de
+simulacion de LTSpice.

+### Soporte Cables
+
+## Construccion de la Placa Base
+
+### Consideraciones
+
+Por la resistencia R2 circulan aproximadamente $11 mA$ según simulación
+independientemente de la carga, esta corriente circula cuando el
+capcacitor C2 se descarga. Esta corriente provoca que la resistencia R2 cuyo
+valor es $1000\ \Omega$ deba disipar $V_{CC}\frac{R2}{R2+RV1}\cdot 11mA$, siendo
+$RV1$ el valor del potenciometro. Para el potenciometro en un $50\%$, la
+potencia disipada por R2 resulta:
+
+$$P=12V\cdot \frac{1000\Omega}{1000\Omega + 25000\Omega} \cdot 11mA = 5mW$$
+
+Por lo que con un resistor que soporte potencia de $0.25W$ resulta mas que
+suficiente.
+
+### Materiales

+Por la resistencia R2 circulan aproximadamente \(11 mA\) según
+simulación independientemente de la carga, esta corriente circula cuando
+el capcacitor C2 se descarga. Esta corriente provoca que la resistencia
+R2 cuyo valor es \(1000\ \Omega\) deba disipar
+\(V_{CC}\frac{R2}{R2+RV1}\cdot 11mA\), siendo \(RV1\) el valor del
+potenciometro. Para el potenciometro en un \(50\%\), la potencia
+disipada por R2 resulta:
+
+\[P=12V\cdot \frac{1000\Omega}{1000\Omega + 25000\Omega} \cdot 11mA = 5mW\]
+
+Por lo que con un resistor que soporte potencia de \(0.25W\) resulta mas
