PA100-D Chip identification

[EA4CKL]

I´ve just received the kit.

First: congratulations for the electronic and mechanical desing.

Second: I have a doubt with the identification of chips IC3, IC11 and IC10 of the Digital Control Module, there is no dot indicating pin number 1. I suppose pin number 1 may be in the lower leftside of the text printed on the chips, that is, where de ST trade mark. ¿Am I right?

Look for one side that is beveled. With the beveled side facing you, the left side is pin one.

By way of illustration, examine the attached JPEG image of a chip from the Juma TRX-2 Filter Module, you can clearly see the 45 degree chamfer on the left-hand side, pin 1 is at the top left-hand corner.
