Pin is .6mm. Hole should be 1.0mm per spec sheet. Will change. + +[ ] Is C26 rated at 25V in BOM? + C26 is 25V in schematic, 16V in BOM. + OOPS! C23, C26, C40 & C46 should all be 25V. Will change database & BOM.

Change? + +[ ] couldn't solder bottom pad of U5 by hand     + hope it's OK + Attached to large gnd plane. Hard to solder. Designed for IR SMT + assembly. Try large iron on vias from bottom. + +[ ] Can R6,R2,R5,R3,R4 be 10k to match R1? + Don't know if 10K will work for R6. Discovery has 680 or small value. + Try it. Can't hurt. + R2 & R5 Are I2C pins. Recommended 4.7K for max speed. Not used now on + SM1000. 10K would limit speed if used. Try it. + R3 & R4 should work with 10K. + Let me know results & I can change values if appropriate. + +[ ] Would VDDA power supply circuit be better located closer to U1? + I think they are pretty close now. I'll look at VDDA function and advise. + +[ ] Larger TAPR/Credits text on bottom?     + there is plenty of room + Tried to get printing without visa & pads in the text. Smallest via has + .016" drill and is tented. I'll enlarge text & see what I can do. + +[ ] What was Vin range meant to be? + VIN is 1 diode drop lower than VEXT(6-16VDC) or approx 5.5 - 15.5VDC Used to power LM386 to get more output swing. + +[ ] move R20 label close to R20     + I loaded R20 in the wrong place! + Will do. + +[ ] is 4k7 missing from BOM or just my order?    + I didn't have any in my Digikey order + Part definition error. Part # in part definition field. Will correct database & BOM. + This affects R2,R3, R4, R5 & R48.

Found that C23, C26, C40 & C46 all should be 25V. That's why I made them separate line item. I'll Change BOM to Digikey part # 490-1524-6-ND Murata # GRM188R71E104KA01D + +[ ] Re CN3, Hmm, now I'm not sure!  I dug around in the shed and found a connector that fits so I'm OK for now. + CN3 is Switchcraft RASM712PX 2.5mm ID, 5.5mm OD Plug.  CONN PWR PLUG DC 2.5X5.5 8A MOD Digikey  # CP3-002BH-ND + I've noted a problem, but will wait til you decide. + +[ ] OK I just check the BOM I have, and there are no 4.7k resistors on it, e.g. R2, R3, R4, R5.  Oh OK, the BOM has a part number.  Not sure what that mapped to on my Digikey order, just noticed I didn't get any 4k7s.  Maybe change the BOM to indicate the part value? + Part database error, invalid part definition. Digikey & Vishay Dale part numbers are correct. Part definition for R2, R3, R4, R5 & R48 should be: RES 4.70K OHM 1/10W 1% 0603 SMD Will correct part database & BOM. + +==================================== -- 2.25.1
