Features and Benefits
1. Intelligent reverse connect protection, the power supply reverse connection does not damage the IC.
2. The control circuit and the LED share the only power source.
3. Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel
point.
4. Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not
accumulate.
5. Built-in electric reset circuit and power lost reset circuit.
6. 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.
7. Cascading port transmission signal by single line.
8. Any two point the distance less than 5m transmission signal without any increase circuit.
9. When the refresh rate is 30fps, cascade number are not less than1024 points.
10. Send data at speeds of 800Kbps.
11. The color of the light were highly consistent, cost-effective..
Applications
1.Full-color module, Full color soft lights a lamp strip.
2.LED decorative lighting, Indoor/outdoor LED video irregular screen.
General description
APA104 is a intelligent control LED light source that the control circuit and RGB chip are integrated in a
package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplifi
cation drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant curre
-nt control part, effectively ensuring the pixel point light color height consistent.
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN
port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch,
the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade
pixel through the DO port. After transmission for each pixel，the signal to reduce 24bit. pixel adopt auto resha
-ping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend
on the speed of signal transmission.
LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angl
e is large, good consistency, low power, long life and other advantages. The control chip integrated in LED
above becoming more simple circuit, small volume, convenient installation.

Note: The data of D1 is send by MCU,and D2, D3, D4 through pixel internal reshaping amplification to
transmit.
Composition of 24bit data:
R7 R6 R5 R4 R3 R2 R1 R0 G7 G6 G5 G4 G3 G2 G1 G0 B7 B6 B5 B4 B3 B2 B1 B0
Note: Follow the order of GRB to sent data and the high bit sent at first.
Typical application circuit:
Note:
1. Don’t open the moisture proof bag before you ready use
2. The led should be kept at 30℃ or less and 60％RH or less before opening package.
3. keeping led over 3 months or reuse led that is kept in open-package, Then please eliminate humid.
Pls use the constant-temperature oven to toast the led at 60℃for 12Hours. or peel led from roll and toast it at 120℃
for 2hours.
4. the temperature of iron be lower 300℃ and soldering within 3sec, Per solder-pad is observed.
