Infineon Shield Q/A

I would like to suggest this place for the exchange of information on this shield. I noticed a Google shows very little practical information, other than recent news announcing the shield. Since I am first, here is my question:

How are people going to power these and what input voltages/output voltages are expected?

Thanks and hoping the information share can benefit all

Thanks @ Peter Oakes and @ alexev ! I finished reading the technical details as much as I could get hands on. Seems like the shield uses I2C commands to configure many parameters from Arduino Uno master…

Currently my plan is to use basic 12V LED strips up to the rated current

So input voltage will be 12 and I expect the output to be the same, I will be interested to see if the shield allows for this kind of hook up, I don’t see why it should not

Unfortunately 12V strips do not want a constant current as their source because of the way there made, but a fixed voltage that can be in the form of PWM on them is OK

For anyone needing information on changing the MCU on the shield.

From the Quick start guide:

NOTE: DC input voltage to the RGB

LED shield should be higher than the

forward voltage of the light engine

Does this allow equal voltage?

probably not but I would imagine close enough, I will look to see what the minimal drop is

As Peter Oakes said, pwm would be the best way to control the led strings using the infineon shield. Pwm gives you an edge when running applications close to your input voltages or higher output ones. As info about this shield is scarce, i think testing and debugging will be the backbone of this project.

Thanks @Peter Oakes and @alexev !

I finished reading the technical details as much as I could get hands on. Seems like the shield uses I2C commands to configure many parameters from Arduino Uno master or Infineon eval board. It uses a PWM design to sawtooth the Mosfets to turn on/off at a rate to match your inputs. The defaults are safe as long as the minimum 300 mA are maintained and the voltage is between 12V and 48V. Stay tuned for more to come.

Please go check @BYOB Party #3, Infineon Library Available for a first hands on look of the Infineon Shield. A great discussion with summary of the parameters that can be set by @Peter Oakes.

Thanks Peter,
Clem

When you get your package, you will need some male long headers(not provided) to connect shield to arduino(uno/yun).

yes indeed, you'll have to improvise somewhat.

I have a feeling that the real testing will be after the projects. I know I at least will want to prove my project will work before I go out and try to see what the card will do. However after the project is done I am open to doing some playing to see what it will really do as I can always replace it.
