This board enables me to use two 12V RGB LED light controllers (check out ebay) for manual control of up to 6 dew heater bands. However I can also switch any or all the channels over for automated control using the Arduino and a temperature / humidity sensor.
This board has two switch ICs that switch over the control signal for each of the 6 channels between the manual Pot and the 6 channel digital Pot on this board.
If you add in 2mm JST connectors / cables and connec the connector from the manual Pots on the RGB dimmers, to this board (CH1_POT….) and then similar connects from this boards outputs (CH1_BO) back to the sockets on the RGB dimmer boards - then you have yourself a SPI controlled 6 Channel Dew Controller.
There are no passive components on the board, only power, ground, ICs and connectors. The power being used by the ICs is 5V.
