+===== Description =====
+Th G-ASH03 board unit an Arduino nano on board can be used for various applications.\\
+Originally designed for controlling 12 servomotors via DCC or Motorola commands,\\
+Here we have a very nice task for this board as well.\\
+The multicour intelligent leds are available in wide setup ups like bars, LED strips, 64 LED boards etc.\\
+To control these LEDs with integrated chip, it takes at least an Arduino nano, but
+it enables you to control all kinds of colours in each led separately, using
+only three wires.\\
+Fred Jansen created firmware for the Arduino to control these LEDs via the Rocrail Dumper library.\\
+Control is established via a controller setup in Rocrail, using "dumper".\\
+Basicly, all you need is an Arduino Uno or Nano board and a sufficient supply of 5 Volt.\\
+Also the G-ASH03 board gives you a very nice start with the multicolour LED adventure.\\
+Rocrail, starting ad version 15816, is ready for it!\\

+==== LEDii Firmware====
+//Alternative firmware by Rocrail.//
+===Features===
+  * Max. 64 LEDs on connector 1.
+  * __**[[:weather-en|Weather]]**__ compatible.
+  * Color outputs with dimming and blinking.
+  * Range addressing to control multiple LEDs with one output.
+  * Simple 3 aspect signal support.
+===Download===

+===Rocrail Setup===
+  - [[:rascii-en|RASCII library]]
+  - Serial port of the Arduino Nano, **9600**bps and no CTS
+The firmware date, yyyyMMdd, is shown in the Rocrail trace after connecting to the Nano:
+<code>info: LEDii 20190821 (c)Rocrail</code>
+===Outputs===
+  - LED number: Port
+  - LED range: Address-Port (Where by address should be less then port.)
+  - The Interface -> Color option must be set
+  - Brightness is set by Interface -> Value
+  - Dimming step is set by Interface -> Delay (0...15) (A value of zero deactivate dimming.)
+  - The Interface -> Blink option may be used to flash the LED
+  - The LED color is set by Color -> RGB
+===Signals===
+  - LED number: Port
+  - Port type: LED
+  - Control type: Aspect number
+  - Brightness
+\\
+====Supply G-ASH03====
+\\
+G-ASH03 by itself does not need much power, but the leds are drawing plm 20mAmp EACH when lit at full intensity.
+This makes the need for a good power supply.\\
+G-ASH03 is equipped with two voltage regulators, originally the same L7805.\\
+But for the leds we need more, so for VR2 we use a HW-613 power supply, wich fits at the same place,\\
+and can deliver 5V by 3Amp.,  where the power to the G-ASH03 can be max 24V dc OR 18V ac.\\
+Supplying the Ledsstrips externally with 5V is also optionable..\\
+If you need advice, please ask [[peter.giling@rocrail.net|Peter]]
+\\
+==== Connections G-ASH03 to LEDstrip ====
+\\
+Ledstrip is connected to servo1 connector in the following way.
+^  G-ASH03 servo1,2,3  ^  ledstrip wire  \\  optionable  ^  function  ^
+|  br  |  WHITE  |  GND  |
+|  re  |  RED    |  +5V  |
+|  or  |  GREEN  |  signal  |
+\\
+==== Different types of Ledstrips ====
+So far, the program controls three different types of led strips:
+  * WS2812B
+  * WS2812
+  * TM1803
+The correct type needs to be selected via a special command in the Arduino IDE.\\
+Please refer to the command manual.\\
+\\
+=== 5V supply for ledstrip(s) ===
+The leds on these strips can consume max 20 mA EACh.\\
+This depends partly on the intensdity to be used.\\
+With 60 leds in one strip the total curent will be 60 x 3 x 0,015 = approx 1 Amp for each colour.\\
+Practicaly, the G-ASH03 can handle one strip 0f 60 leds.\\
+With a supply of 24 V a total current of 0,5 Amp is needed for 60 leds.\\
+In case of higher amount of leds, extra power supply is needed.\\
