16x8 1.2\" LED Matrix + Backpack - Ultra Bright Round Green LEDs

16x8 1.2\" LED Matrix + Backpack - Ultra Bright Round Green LEDsWhat's better than a single LED? Lots of LEDs! And what's better than lots of LEDs? TWO TIMES AS MANY LEDS!!! With the 16x8 LED Matrix Backpack we've doubled your project's matrix capacity by making it super easy to get two separate 8x8 matrices onto one handy board! Matrices like these are 'multiplexed' so to control 64 LEDs you need 16 pins and to control 128 LEDs, you'd need 24 pins. That's a lot of pins, and there are driver chips like the MAX7219

The Volta Racer Solar Motorcar Kit contains all of the necessary parts required to successfully assemble your car - including the worlds first flexible polycrystalline silicon solar cell used for powering toys

Suiting for normal MicroSD card

Power your favorite electronic kit with green energy

Peak Forward Current Per Segment：80 mA

it complies with microcontroller or DC loads

The PWM is built into each LED-chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for you

and two panels for the sides

Weird but fun

This Bit-bang mode pins (8 I/O pins) can be used as a replacement for applications involving PC parallel port which is scares now a day
