Version History SDR PCB

PCB RevReleasedManufacturerFeaturesIdentification
0.1 O281st prototypeRev number in assembly print
0.2 O282nd prototype. Fully operational. Can be modified up to Rev 1.3Rev number in assembly print
1.006/2010O28Version FiFi 2010. Can be modified up to Rev 1.3Rev number in assembly print
1.109/2010O28Improved TOI. Can be modified up to Rev 1.3Rev number in assembly print
1.202/2011FAFirst FUNKAMATEUR editionno assembly print, therefore no Rev number visible. R5=51R, R28=1k, C8 with Plus to the top
10/2011FAEquals Rev 1.3 electrically, but is only a BOM change of the Rev 1.2- PCB (R5=0R, R28=1k5)as above, but R5=0R, R28=1k5
1.3 never manufactured, because same result could be achieved by population change of Rev 1.2, see above
1.406/2012FAOptimized op-amp supply, no GND D/A separationRev number in stop layer, no assembly print, C8 with Plus to the left
1.5 O28, FAinternal prototype for Rev 2.0 with 192 kHz ADCRev number in assembly print and stop layer
2.011/2013FAVersion with 192 kHz ADCRev number in stop layer, IC3=AD1974
