Greetings, can you help reveal a physical pin diagram in SK board docs? I cannot find where in your documentation it indicates locations of PIN1 and PIN40. They could be inverted from user expectations by 180 degrees.
Currently I've found an answer by probing with a DMM. Still searching to match that answer in documentation.
Connector and device pin 1 locations are typically denoted on the assembly drawing with an arrow, star, or '1' notation. Below is from the SK-TDA4VM top assembly drawing with connector J3 (40pin header). It shows pin 1 is located along the edge of the board on end nearest face of the board. All odd numbered pins will be along the edge of the board, even number pins will be on the inside of the connector.
