This is a simple to use RF controller for the WS2811 individually addressable LED strips. Works for both 5V and 12V strips. Features: RF Remote control, with long distance,wire connection is simple and very easy to use; Support almost every kind of one-wire or two-wire LED-DRIVER-IC ;(Can be customized) With 125 kinds of patterns,which are vivid and beautiful; Each controller can control up to 2450 pixels; Preventing reverse connection of power supply. Remote Control: Functions Of Each Button: ON/OFF To control the LED ON or OFF MODE+ Switching patterns forwardly MODE- Switching patterns backwardly SPEED+ Switching speed forwardly SPEED- Switching speed backwardly AUTO Run internal pattern automatically NUM+ Add the number of pixels on each section NUM- Decreased the number of pixels on each section SEC+ Add number of section. SEC- Decreased number of section. MATCH Match the Remote control with the receiving controller Testing and Matching: Pressing the AUTO button for up to 3 seconds until LED is out, release the AUTO button to into the mode of switching in red,green,blue,yellow,purple, cyan and white,witch to test the your LED. Pressing and hold the MATCH button for up to 3 seconds to match the Remote control with the receiving controller. Pressing and hold the MATCH button for up to 3 seconds to un-match. Sections: Some of the patterns run in several sections, each section is the same. User can make the number of sections as follow: 5, 10, 15, 20, 25, 30,35. Pixel number of each section can be chosen as follow: 20, 30, 40, 50, 60, 70 . Sum of pixels = Sections*Number per section User Setting Saving: Users each pressing on the button can be saved by the controller automatically. When the controller is power off, next time power up, it will work the way as the same as before Receiving Controller: Can be customized to support almost every kind of one-wire or two-wire LED-DRIVER-IC . User can specify to support which IC before our delivery,and also,user can modify the status of R5,R6,R7,R8 on the PCB to meet their needs: Actions To support IC Short none of R5,R6,R7,R8 WS2811 Short R5,breakR6,R7,R8 WS2801 Short R6,breakR6,R7,R8 LPD6803 Short R7,breakR6,R7,R8 LPD8806 Short R8,breakR5,R6,R7 UCS9812 Short R5,R6,breakR7,R8 UCS1903,APA104 Short R6,R7,breakR5,R8 APA102 Short R7,R8,breakR5,R6 TM1804,TM1809 The receiver controller is :5V-supply-voltage . Cautions: Please make sure the power supply voltage matches your controller before you power it.
