Hi Brian,
Nice Atmel (ATMEGA16) chip and transistor switching.
You could duplicate this with our friend the Arduino
Board states that each output can switch max. current per channel 1A , in summary max. 5 A ( in summary I think you can take as in total for the whole board)
So 22 channels with max load 5 amp and no one channel more than 1 amp ( but there are 12 8 pin components which would suggest 24 channels)
Not quite sure I understand your original post but you can have multiple LEDS per output so long as the overall current draw in max 1 amp per channel and 5 amp for the whole setup
I would be interested if you could see the component ID on the little DIL 8 pin components

Yes I know about the arduino aspect Jonathon. I have the code from the ship lighting subject on the arduino forum. I just wanted to make use of this board which when I bought it seemed to do everything I wanted. Its a good job I have an Uno and a Mega I'm rapidly running out of outputs!
The uno is planned to manage 4 dc motors, 4 servo's and two steppers up to now, when I can get the code into a workable configuration so it all works together instead of in individual segments
without adding anything else to it. I just might move all that over to the Mega.
The numbers on the chips, and I can tell you this was so tiny I had to take it out in the sunlight, I had on a pair of 2 dioptre magnifying glasses and a handheld 5 dioptre glass and they were still barely legible. .....

Hope that satisfies your curiosity
I think what I'll do is set it up on the bench with some led's attached and see how it goes. I always have the option of falling back to the arduino, but its not my first choice at the moment.
Thanks everyone for your input.
