.96 OLED Mounting Frustrations
Posted: Wed Jan 02, 2019 12:08 am
The .96in OLED screens I've found have 4 pins at .1in spacing
Depending on the MMDVM board, the OLED header can be either wired to the STM32 chip or the GPIO header. Since the software (MMDVMHost and/or
MMDVM firmware?) does not support OLED, if wired to the STM32 the OLED header is not functional. The ZUMspot is an example of such a board (will be changed in a future version).
If wired to the GPIO the OLED header is functional, but mounting the screen to it results in a physical screen position that is not centered over the board making installation in a case difficult or impossible.
Mounting the screen directly to the GPIO can result in good physical placement. With JumboSPOT boards this is easy. The JS only has female "pins" installed on the first 5 pairs of the GPIO headers (pins #1-#10?). The OLED screen pins can be soldered into holes 12/14/16/18.
With the ZUMspot and DB9MAT/DF2ET boards this is more of a challenge since all GPIO header positions have female "pins" installed.
This is a summary based on information I've gathered from various sources. Hopefully some of it is incorrect. Comments and corrections are welcome.
