This could work with a lsu 4.2 ?
I saw that the pcb has R7 to deal with but the software can ?

Finally got around to finishing this up, everything is now done and tested. I will put up a new git repository with the completed files later this week.
I am going to offer 3 different kits:
SLC Free A: open source, LSU 4.9 sensor only, LCD displays lambda and sensor temperature as bargraph, $35 USD
SLC Free B: closed source, LSU 4.9 sensor only, LCD displays lambda and sensor temperature as numeric text, $45 USD
SLC Free C: closed source, LSU 4.2 sensor only, LCD displays lambda and sensor temperature as numeric text, $45 USD

I take it the baragraph doesn't tell you anything but how far its from one side of the range to another vs the numerica text saying what its current temp is?

Will the SLC-Free be able to use I2C?
What is the accuracy difference between the SLC-OEM and SLC-Free?

The bargraph is actually pretty decent, there are 80 columns so and each column represent 0.01 lambda increments. What I will try to do is make a paper template that you can cut out and paste onto the display PCB which will give you visual cues on where along the column represents what lambda value. _________________www.14Point7.com

What is the accuracy difference between the SLC-OEM and SLC-Free? I do not do any calibration on the unit, so SLC Free is at the mercy of component tolerances and the analog system on the PSOC uC. For SLC OEM, all units go through quality control, and I do some calibration on them before they ship out, so I am 100% confident that it is 0.01 lambda accurate. For SLC Free I have built about a dozen of them over the course of development, and 70% is 0.01 lambda accurate, the other 30% is in the 0.02 lambada accurate range. I2C is not supported by SLC Free _________________www.14Point7.com
