1 Bảng Đèn Led Max7219 8-digital Ws2812B 16-bit 4x5050 Cho Arduino

1 Pcs LED Display Tube ule and 1 Pcs LED Lamp Panel RGB light source ule
LED Display Tube ule:
MAX7219 is an integrated serial input / output common-cathode display drivers, which connects the microprocessor and 8 digit 7-segment digital LED display.you can also connect a bar graph display or 64 separate LED.Includes an on-chip type B BCD encoders, multi-channel scanning loop, segment word driver, but also a 8x8 static RAM that stores each data.
Only one external register is used to set the current of each LED segment.A convenient four-wire serial interface can connect all common microprocessor.Each data can be addressed in the update without rewriting all displays.
MAX7219 also allows the user to select each data encoding or no coding.The entire device includes a 150μA low-power shutdown e, analog and digital brightness control, a scan-limit register allows the user to display 1-8 bit data, there is an all LED light detection e.material:CCL
Only need three IO ports can drive eight digital tube!
Note:VCC and GND do not reversed, it would burn the chip
51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines
size:8.2*1.5CM/3.35*0.59 inch
colour:BLUE
LED Lamp Panel RGB light source ule:
The control circuit and the LED share the only power source.
Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point.
Built-in sign
all reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
Built-in electric reset circuit and power lost reset circuit.
Each pixel of the three primary color?can achieve 256 brightness display completed 16777216 color full color display, and scan frequency not less than 400Hz/s.
Cascading port transmission signal by single line
Any two point the distance more than 5m transmission signal without any increase circuit.
When the refresh rate is 30fps, cascade number are not less than1024 points.
Send data at speeds of 800Kbps.
The color of the light were highly consistent, cost-effective..
Color:Black
Package includes:
1 x LED Lamp Panel RGB light source ule
1 x LED Display Tube ule
Only the above package content, other products are not included.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1
