Leading Edge AC Dimmer.
Module contains 8 Triacs with zero-cross detector for programming the intensity
of incandescent lamps, heating elements, AC LED dimmable bulbs or fan speed controlled through a micro-controller.
Working AC voltage 80v to 240v.
Auto detect 50Hz or 60Hz.
Zero-Cross detection (with zero/cross output pin SYNC).
Compatible with any ARDUINO, RASPBERRY boards.
Low voltage side and high voltage side is completely isolated.
Dimensions of the PCB 131mm x 91mm (5.16inch x 3.58inch). Four mounting holes diameter 3.2mm (0.13inch).
Connected LOAD current for each channel 2A long-term, short-term 5A.
NOT appropriate to change the brightness of fluorescent lamps !!!
Not for controlling via PWM signal !
Descriptions of pins:
GND -> ground of low voltage side
VCC -> device power, DC 5 volts
SYNC -> zero-cross detector output positive impulse (pulse length 200us)
CH1 -> triac gate input pin for 1 channel
CH2 -> triac gate input pin for 2 channel
CH3 -> triac gate input pin for 3 channel
CH4 -> triac gate input pin for 4 channel
CH5 -> triac gate input pin for 5 channel
CH6 -> triac gate input pin for 6 channel
CH7 -> triac gate input pin for 7 channel
CH8 -> triac gate input pin for 8 channel
AC INPUT -> AC voltage input 110/220
AC LOAD -> Connect your load here for 1ch, 2ch, 3ch, 4ch, 5ch, 6ch, 7ch and 8ch
How to connect to Arduino UNO board :
GND - > GND
VCC -> 5V
SYNC -> DIGITAL.3
CH1 -> DIGITAL.4
CH2 -> DIGITAL.5
CH3 -> DIGITAL.6
CH4 -> DIGITAL.7

I bought this card (8 Channel AC Light Dimmer Module Arduino). Using it with single dimmer card sketch it works perfectly but with 8ch sketch the lights start flickering when are dimmed to lowest values. Any suggestion?
I have seen your AC dimmable led bulb video here https://youtu.be/oqRyJLcfOxo
Does the led bulb turn off completely when you make the dim level to 0% ?
How much is the off condition voltage of these dimers. ? In case of triac ac dimmer if its dimmed to lowest value (0%), it still gives some AC voltage. This is ok for fan and incandescent bulbs, but not good for LED bulbs. Also this standby voltage will consume electricity. Let me know what if this dimmer has similar problem?
after connecting and testing, the board dosen`t seem to work with a Raspberry directly.
Is that right ?
Only when I put an Arduino between and send with Python commands from Pi to arduino via serial port. but this is not really comfortable.
There was no manual in the package.
And all the shown sketches and descriptions are for the using with Arduino.
But there was written:
"Compatible with any ARDUINO, RASPBERRY boards."
Could you send me some sketches how it should look like for using a Pi?
