Soft as a Feather Pillow (SFP) SSR Soft Start Circuit GB

[Oneminde]

Comparing v.2.2 against v2.3, the latest iteration got rid of the indicator LED's which could be routed to the front. I enjoyed this feature of v2.2. Would there be any issues moving forward with v.2.2 or does it have stability issues ?

As I see it, the option still exists. You can load the on board status LEDs or off board via the associated headers. Just not both.

Just such that there is no confusion

v.2.2

v2.3

I can see use cases for both and one doesn't always need additional status information such as can be see on v2.2 nor a momentary switch... but I like that stuff so in light of that, I will stick to v2.2.

Gonna be interesting what is cooking in your brain for v2.4 .. who knows what untapped potential you see

The version history is not applicable here because the through-hole SFP board is a different design compared to the smt SFP+ board.
Apples to oranges 😁

Vunce is correct. These are two different boards (products). Unfortunately, they have similar names and the rev numbers are similar at circa 2.2/2.3.

SFP (soft as a feather pillow) has no remote on/off capability. Just soft start. Latest is 2.3

SFPP (soft as a feather pillow plus) has remote on/off capability plus remote shutdown due to safety trigger. Latest is 2.2.

I am working on an update to SFPP that doesn’t use those pesky SMT flip flop and NANDs with tiny hidden solder pads.

Aah, I didn't think about the TH vs SMD... kewl. Thanks for pointing it out, besides the other attributes.

So the newer SFPP will use easier to solder parts ?

 

[xrk971]

Yes. Still SMT but SOIC14 vs crazy tiny 3mmx3mm package TSSOP-8 with 0.65mm pitch legs. Very hard to solder without getting a bridged pad.

Looking forward to seeing it

SFPP looks like really nice board! Looking forward to use one in my builds!
