Why was the chip changed from the MAX31855 to the MAX6675?
strictly logistical. we were faced with either delaying the initial release by 4-5 months, or using the 6675. so we went with the more expensive 6675 just to get the ospid out the door. the 31855 is now available in steady quantities and is used in v1.2 of the input card. v1.2 is what we’re now selling. the 6675 was strictly a first-batch thing.
