Spark Fun refer abou great new toy at Embedded Systems Conference in San Jose. Many fun, many new and upcoming products and many very cool customers.
The LED Light Bar is a pre-packaged strip of 3 high-output LEDs powered by 12VDC. We don’t have specifics on the output luminocity, but take a look at the example GPS Wall Clock project to get an idea. Each unit comes with a fully assembled and tested PCB with current limiting resistors, reverse protection diodes, a wall-mount holder (backed with double-stick tape), and a connection cable. Each LED Light Bar absorbs approx. 30mA @ 12V.
And There is one more great toy for LED matrix geeks.
Triple Color LED Matrix! This large matrix has 64 Ultra Bright-Red, 64 Ultra Bright-Green, and 64 Ultra Bright-Blue individual LEDs built into one common cathode housing. It’s a monster to control, but just imagine what kind of colors you could produce by mixing!
