Francis,
Here is the list of required photos so far:
Photo 1: The STM32 Primer (original Primer1)
Photo 2: The STM32 Primer2 with original Primer for size comparison
Photo 3: Contents of Primer1/Primer2 packaging
Photo 4a: Primer1 PCB backside detail showing expansion footprint
Photo 4b: Primer2 PCB backside detail showing expansion connector and SD slot
The lead time for these articles from submission to publication can be several months. Having access to the latest CircleOS and documentation will be of great help. If all goes well, it could even be ready before the deadline for the new contest, which I think would be good for getting some more exposure for the event.
Thanks,
Dale Wheat
