Hello! We just wanted to remind you that The United States Postal Service is closed today for Presidents Day. Any orders placed using USPS will not ship until tomorrow, February 20th. Have a great day!
This is a basic 16 character by 2 line display with a snazzy black background with white characters. Utilizes the extremely common HD44780 parallel interface chipset (datasheet). Interface code is freely available. You will need ~11 general I/O pins to interface to this LCD screen. Includes white LED backlight.
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.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

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.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Tuve que cambiar la primera que compré porque empezó a oiscilar la iluminación de la pantalla.
Por lo demás todo muy bien, buena presentación y buen funcionamiento.
The display is clear and the characters are legible. I do wish this display supported more than 32 characters. As for interfacing, that is very easy. Just a hand-full of switches (and one potentiometer) and an ASCII chart you don’t even need a microcontroller (but you’ll only be able to print one character every few seconds without one).
Display is Much brighter than the picture, and even though it was a bit scary to solder onto (im a bit of a newb at soldering) , it works fantastic! So bright, Very responsive. I dont even have the display at its brightest and it is a crystal clear read! Look forward to using it in my summer project.
The LCD arrived promptly in the mail and worked as advertised. If my experience is typical of Sparkfun, they have good products and are very efficient.
I wired up the display and ran it with the standard Arduino library. Worked first time!
Apparent color changes from white-on-black to black-on-white at ~ + 5’ and ~ -20’. Readable until ~ + 35’ and ~ - 80’. During the color change, it’s difficult to read; a lot of head bobbing is required. Readability at greater + angles would be better for my application. Is there any way to flip the text orientation or, perhaps, another hack to improve upon this issue? I won’t be purchasing this product again.
Shipped defective,,didn’t work
Sorry to hear about the issues with the LCD screen. Have you contacted our technical support department @ email@example.com - they’re usually great at helping sort out defective products for people and getting them working components.
I used this display in a DDS VFO. The contrast of the display is great for viewing at any angle day or night
This LCD works as advertised. The software compiles from the Arduino library only for version 1.0.5-r2. These LCD units are well made, but do not drop them on a hard surface as the electronic seal to sensitive glass surface will fail to make proper contact. Most of the test examples in the Arduino library work great. My unit shows black on white.
I bought it to fit into a homebrew DDS-based VFO for my vintage ham station. Most of the various color displays just don’t look right with all the dark somber enclosures of the period. This mostly monochrome LCD fits in fine if one can accept a DDS device in a tube environment.
But it’s certainly bright and showy INSIDE with it’s red PCB.
