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.
This product comes as a kit! Included is a high quality PCB and all the components (buttons, header etc). A 16×2 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. Check the product tutorial page for assembly instructions before purchasing.
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).
