Makers, developers and hobbyists that may be looking to add a little colour to their projects for the holiday season might be interested in the new NeoPixel Mini 3535 RGB LEDs, which are now available to purchase via the Adafruit online store priced at just $4.95 for a pack of 10.
The tiny RGB LEDs measure just 3.5 x 3.5 mm and are half the size of the standard NeoPixels but are still fairly easy to solder into place and provide an easy way to integrate multiple bright LEDs into a design.
Adafruit explains more about the new addition to their range :
The LEDs are ‘chainable’ by connecting the output of one chip into the input of another – see the datasheet for diagrams and pinouts. To allow the entire chip to be integrated into a 4-pin package, there is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc.
It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the Netduino or Basic Stamp. The LEDs basically have a WS2811 inside, but fixed at the 800KHz ‘high speed’ setting. Our wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.
