We really like the RGB Character LCDs we stock in the shop. (For RGB we have RGB negative and RGB positive.) Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 3 to control the RGB backlight for a total of 9 pins. That's nearly all the GPIO available on a Pi!\u003cbr\u003e\u003cbr\u003eWith this in mind, we wanted to make it easier for people to get these LCDs into their projects so we devised a Pi plate that lets you control \u003cstrong\u003ea 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi!\u003c\/strong\u003e 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.\u003cbr\u003e\u003cbr\u003eThis pi plate is perfect for when you want to build a stand-alone project with its own user interface. The 4 directional buttons plus the select button allow basic control without having to attach a bulky computer.\u003cbr\u003e\u003cbr\u003eThe plate is designed for both Revision 1 and Revision 2 Raspberry Pi's. It uses the I2C (SDA\/SCL) pins. We have a special extra-tall 26-pin header so the plate sits above the USB and Ethernet jacks. \u003cstrong\u003eFor Pi Model B+ and Pi 2\u003c\/strong\u003e, 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThis product comes as a kit!\u003c\/strong\u003e Included is a high-quality PCB and all the components (buttons, header etc). \u003cstrong\u003eA 16x2 Character RGB negative LCD is included!\u003c\/strong\u003e Assembly is easy, even if you've never soldered before and the kit can be completed in 30 minutes.  Check the product tutorial page for assembly instructions before purchasing.\u003cbr\u003e\u003cbr\u003eWe 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.\u003cbr\u003e\u003cbr\u003eAt 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 colours: Red, Yellow, Green, Teal, Blue, Violet, White and all colours turned 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 colours, this plate can't do that (the I2C expander does not have PWM output).\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: We've updated this Pi plate so there are buttons on the right side which makes it a little more mechanically stable.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"panel-collapse collapse in\" id=\"tab-technical-details-content\"\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 2.2\" x 3.35\"\u003c\/li\u003e\n\u003cli\u003eComes with a 16x2 RGB NEGATIVE LCD\u003c\/li\u003e\n\u003cli\u003ePlug and play with any Raspberry Pi\u003c\/li\u003e\n\u003cli\u003eUses only the I2C (SDA\/SCL) pins\u003c\/li\u003e\n\u003cli\u003eThis board\/chip uses I2C 7-bit address 0x20.\u003c\/li\u003e\n\u003cli\u003ePCB files, schematic, and Fritzing available in the product tutorial\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Guide\u003c\/li\u003e\n\u003cli\u003eDownloads and Schematic\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":53697470759188,"sku":"fem1787257134185","price":18.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/9486\/7220\/files\/adafruit-rgb-negative-16-x-2-lcdkeypad-kit-for-raspberry-pi-discontinued_1.jpg?v=1787257138","url":"https:\/\/regalwearstore.shop\/products\/adafruit-rgb-negative-16-x-2-lcdkeypad-kit-for-raspberry-pi-discontinued","provider":"My Store","version":"1.0","type":"link"}
