To be able to connect both flow sensors to the aquaero you will need a
y-adapter cable. Since both devices use the same controller board they will also use the same aquabus ID number by default. You have to connect one of these sensors via USB and change its aquabus ID number in the system tab. Each number must be unique. It is like an IP number in a network
If you do not want to use the USB cables for the sensors anymore, you will also need two
aquabus 4-pin cables in addition. These cables can provide power for the sensors through the aquaero.
As far as I know the EK D5 PWM pump like any other D5 pump (with exception of our version
) violates Intels PWM specifications since they are missing a pull-up circuit for the PWM signal. So if you want to control these pumps with the aquaero you have to do a little modification
like this one here. You could use a y-cable to connect both PWM headers to a fan header. Only one pump can be connected with its rpm signal an both pumps must be connected to the PSU for power.
If you follow this example you will have three fan channels left. Of course you can connect further y-adapters or splitter to connect a group of fans to a single channel.
You could use the 2-pin PWM ports to control (brightness) LED strips for example. These ports provide 12V so make sure that whatever you want to attach there is designed for 12V. To connect stuff to these ports you have to use these
2-pin plugs.
The RGB LED port offers more options but is designed mainly for this
LED module. This port can only power one LED so do not try to connect something else because it could damage the device.
