I've printed the calibration when Pot R9 is in the extremes. It looks quite different from what you sent earlier: Non optimal calibration: R9 rotated fully counter-clockwise: VPP calib. offset:...

And perhaps a little explanation of what the Index [x] means. The Digi POT has 128 positions (or taps) and each position provides a different resistance. Each POT position (or...

Hi, it looks like the issue is mt3608 module. I thought this type of the module is the older (good/working) type, but it looks like it is not. Just yesterday,...

I did a few tests. The new modules can be used be used without desoldering the pot by replacing the 2k2 resistor by 12k or 15k (possibly 18k) resistor. It...

Thanks for the feedback - it's good to know 18k resistor works well. I'm glad it finally works for you. > This makes it easier to test one MT3608 module...

I think this issue/solution might be helpful to others, so I'll keep it opened for others as a reference. I usually do not close issues for that reason, it easier...

One more thing. I just noticed your calibration listing. This particular line is unusual: *Index for VPP 1650 is 114 Usually, when (during the 's' command) the maximum voltage is...

OK. looks good. Deviation of - 0.1V to +0.05V should be OK, most of the GAL chips will work fine. And if not, the GAL chip will not be fried/bricked....

Also remember, when you swap the Afterburner (ie. the one made on PCB and the one made on breadboard) you should recalibrate. That's because the resistors for sensing (voltage dividers),...

That's interesting. Is the ATF22V10C brand new? If you write the fuses (with error) and then read the fuses back (r command) - can you at least see that some...
