Este proyecto consiste en un módulo diseñado para proteger los pines GPIO de la Raspberry Pi y extender su funcionalidad. El módulo incluye protecciones con diodos Zener y resistencias, un extensor de pines GPIO, la capacidad de conectar un módulo relé, y un módulo de reloj en tiempo real (RTC) DS3231.
Características:
- Protección de GPIO: Cada pin GPIO está protegido con un diodo Zener y una resistencia de 330 ohms, protegiendo los pines de la Raspberry Pi contra sobretensiones y corrientes excesivas.
- Extensión de Pines GPIO: Se incluye un extensor de pines GPIO que permite la conexión de más dispositivos o módulos adicionales. Compatibilidad con Módulo Relé.
- RTC DS3231: Se ha agregado un módulo de reloj en tiempo real (RTC) DS3231 para mantener el tiempo con alta precisión incluso cuando la Raspberry Pi está apagada.
- Indicadores LED: Se incluyen LEDs de estado en los pines GPIO sin un consumo excesivo de corriente.

Questions
How big is the Module RPI PCB?
It measures 110.2 × 79.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Module RPI use?
172 parts, built around the DS3231MZ+. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Module RPI KiCad files?
From the Danielfgb/RPi-Protector-Extensor-GPIO repository on GitHub, at the commit this page was made from: the board is Module_RPI.kicad_pcb and its schematic Estado_GPIO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Module RPI design in my own project?
Its repository states no licence, so its author keeps all rights: ask Danielfgb before reusing the design.
