Alphanumeric displays are pretty neat. Use them for numbers, use them for letters, or both. They are a good size and brightness for easy reading. The decimal digits aren't connected, so keep that in mind when ordering.
We also carry these in red and greenish yellow.
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.

oh my god, why anode? it is way easier to control common cathode displays, because we work with positive digital pulses. I gotta ask the same thing about the goddamn useless LATCH hall sensor available here too, so useless, who would need a tiristor-like(latch-state device too) hall effect sensor? I really feel sorry for my money.
Yeah. I HATE it when people put the collector side of an NPN on GROUND. It's controlling stuff COMING INNNNN!!!
Be Warned: Because these are BLUE and blue LEDs require more voltage and the bigger segments on the display are actually TWO LEDs in series, 5V through the dual-dot segments is barely visible. Meaning, hooking these up to a 5v system (Arduino) isn't quite as easy as you would think.
I'm Going to try this out with a constant current LED driver IC and a little-bitty step-up regulator.
can I get a link to a similar Alphanumerics availble on mouser, digi-key or element14 ?
Why aren't the decimals connected??
you don't happen to be related to Adam Savage do you?
if you make a version of this with a serial backpack i will worship the ground you walk on.
Heck yeah!
