UA726 substitute for Kobol Expander I (Rev2)

2 layer board of 0.67 x 0.50 inches (17.0 x 12.7 mm)
Uploaded: August 26th 2022
Shared: August 26th 2022
Total Price: $1.65

Untested PCB but got very minor changes from Rev1 which tested fine.

Pins 5, 6, 7 and 8 don't need to be connected.

The two pins on both LM3046 ends are for a 1k 3300ppm PTC (tempco) resistor. It replaces R90/R168 so don't keep it on the VCO board…

UNTESTED YET !

Because the 4 center holes are not metallized inside, you VERY likely have to let a space between the 2.54 connectors plastic support and the PCB in order to be able to solder the pins to the backside pads.
