Hello, I have a question before starting the soldering process, can you confirm me the diode is correctly oriented ?
Thank you !

Ergonomic, split and other weird keyboards
Rules
Keep it ergo
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

While true, you would have to change the firmware to swap column and row polarity if you reverse all the diodes e.g.
#define DIODE_DIRECTION ROW2COLin QMK. Conventionally, QMK assumes rows are on the cathode side of the diodes and drives the columns high.ROW2COLreverses that so that the rows are driven high and columns scanned instead.It's best to stick to the convention so you avoid surprises.
