As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
The review by Glenn in Texas was accurate and helpful. However, the unit works well, and at the current sale price $0.29 its a steal.
Note this is a multiplexed display. I used an Arduino Pro Mini to drive it. To improve contrast, I used a little piece of Duck Brand Translucent Tail Light Tape costs < $4 at WalMart. If you dont need the individual big LEDs at the bottom of the display, you only need to plug the top pins into a standard 0.1 inch pitch breadboard.
I hooked mine up to a DS3231 real-time clock, and wrote code to create a scrolling date/time display. Works great!

Data sheet not quite complete
The data sheet is accurate for what is reported, however here are some stats that are not included:
Digits are approx. 5.8mm H x 3.3mm W - they are small.
Useable forward current is about 5.0 mA - any more and the segments bleed over to adjacent segments.
The pins in a given row are on 2.54mm centers, however, the distance between the upper and lower rows is not a factor of 2.54mm - so dont expect these displays to plug into a proto-board or breadboard without bending a full row of pins.
The pins on the bottom row are approx. 6mm long while the pins on the top row are approx. 3.5mm long.
Still a lot of digits and LEDs to tinker with.
