** PRODUCTO DE ALTA CALIDAD, FABRICADO EN USA POR ADAFRUIT, NO CHINO ! **




Este Hat hace que tu flamante Raspberry pueda lucir una pantalla LCD para mostrar textos o datos. Además, la pantalla LCD de 16x2 es de tres colores y los podrás controlar por software a tu gusto. Por ejemplo, podrás iluminarla en rojo si tu Pi no está contenta o en verde si todo va bien :) Por si fuera poco, el kit dispone de 5 pulsadores que podrás utilizar como punto de entrada del usuario.

Para controlar tanto la pantalla como los pulsadores, el Hat utiliza el puerto I2C, con esto por un lado no desperdicia los otros pines GPIO y además puedes seguir contectando sensores que utilicen ese mismo bus!

Se entrega en forma de kit y requiere soldar los componentes. No es difícil, pero quizás tome unos 30 minutos en tenerlo todo funcionando. Además, está disponible una librería en Python para sacarle provecho desde el primer minuto.


** COMPATIBLE CON CUALQUIER RASPBERRY PI **



With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a Pi plate that lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi! The best part is you don't really lose those two pins either, since you can stick i2c-based sensors, RTCs, etc and have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle.

This pi plate is perfect for when you want to build a stand-alone project with its own user interface. The 4 directional buttons plus select button allows basic control without having to attach a bulky computer.


* The plate is designed for both Revision 1 and Revision 2 Raspberry Pi's. It uses the I2C (SDA/SCL) pins. We have a special xtra-tall 26-pin header so the plate sits above the USB and Ethernet jacks. For Pi Model B+ and Pi 2, the resistors sit right above the new set of USB ports. To keep them from shorting against the metal, a piece of electrical tape must be placed onto the USB ports.


This product comes as a kit! Included is a high quality PCB and all the components (buttons, header etc). A 16x2 Character RGB negative LCD is included! Assembly is easy, even if you've never soldered before and the kit can be completed in 30 minutes.

We also have some handy Python code to help you easily talk to the LCD and buttons. You can also easily query the 5 keypad buttons to get input through the library, so you get extra buttons without using any more pins. The buttons are automatically de-bounced inside the library.

At this time, the code and plate can control the RGB backlight of our character LCDs by turning each LED on or off. This means you can display the following colors: Red, Yellow, Green, Teal, Blue, Violet, White and all off. There is no support for PWM control of the backlight at this time, so if you need to have more granular control of the RGB backlight to display a larger range of colors, this plate can't do that (the I2C expander does not have PWM output).
