info for relay expansion box
sorry but is possible i have the Relay Expansion Box whit 8 outlets pwm for LEDS?
Re: info for relay expansion box
No, but you can add a PWM expansion module to your RA and have 6 more for a total of 8 PWM channels.
If you need more, add a 2nd PWM expansion for a total of 14.
So, basically each PWM expansion module can give you 6 more channels.

but on the site where this PWM expansion module?rimai wrote:No, but you can add a PWM expansion module to your RA and have 6 more for a total of 8 PWM channels.

but this PWM is 8 bit or 12 bit?

Sorry, not yet available at the store but some people already have them. Special order only for now.

but where is the price?
if you're not going to produce it is possible to have the eagle files and code to arduino?

Re: info for relay expansion box
u have a manual in this mode i see if it is possible but in my rarimai wrote:It's $89 plus shipping.
i want see the tipe of connection
i f u want is possible send to

Re: info for relay expansion box
It will work on a 2nd gen relay box. If you have a usb like port on the side of the box, it will work.

but this module use the normal library?
the pwm is 8 or 12 bit? for me this is important
Re: info for relay expansion box
Yes. just add a simple function and you are good to go. Curt is working on getting them into the development libraries too.
The PWM resolution is 8 bit, but to be honest, we don't even use 7bits resolution. We calculate PWM in percentage from 0 to 100, which is less than 7bit resolution.
Even with less than 7 bit resolution, the human eye can't distinguish the difference in my opinion, let alone corals.
Would you be able to enlighten us on why 12 bit would be more beneficial?

for me is importan 12bit for a new project not for aquarium
Re: info for relay expansion box
Got this in, just needs to be tested for the output. It should work because all the code is based on what was already created. I just gave it a main menu entry:rimai wrote:Yes. just add a simple function and you are good to go. Curt is working on getting them into the development libraries too.
and a fancy menu to itself: Note: This code only works with the PWM expansion module. It does not affect the 2 PWM outputs on the controller.
