In my experience, the standard phyWhisperer 2-pin jumpers on J4 can be a bit difficult to grab and rearrange without using pliers due to the recessed jumper location within the enclosure. The 10mm jumpers are just a bit too short to get without special effort, so I’ve searched for extra-long jumpers that are more comfortable to use.
The 14mm jumpers from Harwin that I found at Mouser work quite nicely, so I can recommend them here. There might be similar designs from other vendors as well.
- Harwin M7682-05, black with gold contact finish option (durability)
- similarly M7681-05 and M7683-05 for other colors
Maybe this is an interesting option for future production runs.
