–I recently soldered headers to my DL40. I was successful but had problems, untypical of my other GHI experiences; soldering on all of their other modules has always been fast, easy, and the finished products were attractive.
I’m wondering if maybe this DL40 just got a little too much solder-resist or something at the factory. All of the pads seemed to resist bonding with the solder; some of them would just hang a well-bonded bubble on the pin rather than flow into the pad. I started with lower heat and increased up to what I felt comfortable applying, so close to the CPU. I carefully re-re-re-re-re-touched-up many of them with lots of cooling time inbetween, but some still look like a first-grader did them and will forevermore…
I haven’t tested every single pin yet, but was eventually satisfied enough, visually, to go ahead and plug it in.
Has anyone else experienced this?
–Also, in the attached clip, why does the LED on the DL40 immediately become lit and/or not dim when the neighbor bus is reset (like the PulseInOut’s does).
The DL40 appears to initialize and operate as expected; the blinking LED is being controlled by it.
