Re: uBitx Relay K3 Pins 1 and 5 Location

Yes, there is a relationship, but obscure. The data sheets are wrong. Some dummy mirror-imaged them in an attempt to produce a view from below. Theirs is an attempt at IC-numbering, but flipped end-for-end.  The diagram itself is fine if viewed from above, but the IC numbering should be taken with the 'dot' (pin 1) at bottom-right, 'notch' to the right. The extra gaps are the absent pins 7 and 10.
