Hi,

I have found the problem. Shield has a 1 nF capacitor on the reset line and Arduino has a 100k pull-up. This causes the pin to create a slow startup from logic 0 to logic 1.

Solution: Remove the capacitor or change the capacitor value, meaby 100 pF.

Hi,

I am using Lambda Shield 2 and now creating a cover. Do you have a step model for Lambda Shield 2. It would help me a lot.

Thanks
