MAX7219 Dot Led Matrix Module MCU LED Display Control Module Kit For arduino ()MAX7219 is an integrated serial input / output common-cathode display drivers , which connects the microprocessor 7-segment digital LED display with 8 digits , bar graph can also be connected monitor or 64 separate LED. On type B BCD encoder includes an on-chip , multi-channel scanning loop , segment word drive, but also a 8x8 static RAM for storing each data . Only one external register is used to set the segment current for each LED .A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update does not overwrite all of the display . MAX7219 also allows the user to select each of the data code or not coded .The entire device includes a 150μA low-power shutdown mode , analog and digital brightness control , a scan-limit register allows the user to 1-8 bits of data , there is an LED light so that all the detection mode .Requires only three IO ports can drive a dot ! No flashing dot matrix display ! Support cascade !

New Led Ring 16x 5050 RGB LED Board with Integrated Drivers Module Geekcreit for Arduino - products that work with official Arduino boards ()16 ultra bright smart LED are arranged in a circle with 1.75" (44.5mm) outer diameter.The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together!Each LED is addressable as the driver chip is inside the LED.Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim.Power the whole thing with 5VDC (4-7V works) and you're ready to rock.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 microconroller such as an AVR, , PIC, mbed, etc.It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp.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.Comes as a single ring with 16 individually addressable RGB LEDs assembled and tested.Add to Cart7.14€ -
New LED Ring 24 x WS2812 5050 RGB LED with Integrated Drivers ()24 ultra bright smart LED Ring are arranged in a circle with 66mm outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together!

LED breakout module ()This is a breakout board for the WS2812B RGB LED. The WS2812B (or "NeoPixel") is actually an RGB LED with a WS2811 built right into the LED! All the necessary pins are broken out to 0.1" spaced headers for easy bread-boarding. Several of these breakouts can even be chained together to form a display or an addressable string.Add to Cart4.17€ -
