LCD Keypad Kit for Raspberry Pi - 16x2 (Blue and White)

Let's talk about LCD Keypads: everyone loves them and everyone can find a use for them but they seem to be limited to the Arduino field. What about the Raspberry Pi? Our friends over at Adafruit have come up a really nice LCD Keypad Kit for the Raspberry Pi that can be easily assembled and start being used as soon as you are done soldering it together! With this kit you will be able to easily control a 16x2 character White on Blue LCD, three backlight pins, and five different buttons using only two I2C pins from the Raspberry Pi.

The LCD Keypad for Raspberry Pi consists of a 16x2, white character, blue backlight LCD with a keypad consisting of 5 keys — select, up, right, down and left. To save the digital IO pins, the keypad utilizes the resourcefulness of the MCP23017 I/O expander IC which uses only two I2C pins and in return provides 16 general purpose pins.

Since this is a kit some soldering and assembly will be required before use but once complete you will have a fully functioning LCD Keypad that can be plugged into your Raspberry Pi and start being used right away.

Note: This is the blue and white LCD Keypad kit so you will need to break off a piece of 16 pin header from the stick in the kit and leave the two rightmost pads empty.

LCD Keypad Kit for Raspberry Pi - 16x2 (Blue and White) Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

2 Soldering

Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    Is this pin compatible with a Pi B+ -- using the original Pi B cables?

    The backlight is working, but I'm just getting boxes, no text. Does that mean I screwed up assembly somewhere along the way?

    Is that the Adafruit logo I see? I'm confused...

    • Yep. See also the second sentence of the description, which begins:
