Thanks for helping out Bob, sometimes I get ahead of myself. Dave, you can also trace the wiring on the photo I had sent of the actual module, its more or less clearly visible under the lupe. Please note that on that module I mounted the IC upside down, with the pins sticking up, and bending the grounded pins down toward the PCB. bye, Said In a message dated 10/18/2014 17:55:36 Pacific Daylight Time, kb...@n1k.org writes:
Hi The 20 MHz connects only to pin 3. +3V connects to pin 4 , but not pins 2 or 3. Pin 6 hooks only to pin 2 and nothing else.
