Hi,

could anyone tell me which one is pin 2 on the extension header?
Near the power connector or at the opposite side?
At the upper (toward me when i look at it) column or at the column toward the board?

Thank you,
Steffen

Pin 1 & 2 are near to the battery jumper, and L3 inductance.
The pin 1 is tagged by by a white silk line.

Acording to STM32-Primer2 User Manual pin 2 is indicated with white lite (closer to PCB) and pin 1 is siting on top of it (if you are looking at the bottom side of PCB).
I know one thing for sure: USART TX, USART RX and both ground pins are closer to PCB surface.
