If I ever make a board with a parts count that costs over $1, I will be sure to add diode protection.
Semi-related, does anybody know if there’s a way for KiCad to have “snippets”? It’s really annoying to make the power circuit from scratch/copy it from another schematic every time.
Have to disagree with you here. 
The protection circuits are not just there to protect the module, but also the PSU and the entire system.
KiCad really does a poor job of cutting and pasting or otherwise enabling reuse of circuit elements. You can do it by misusing hierarchical sheets but it’s a pain.
What I’ve done is I’ve made a Kosmo module project template that includes the power section.
Ahhh, I hadn’t considered this. I thought it was just to prevent the IC from blowing up.
It’s also said to be good practice to put the 100 nF bypass caps close to the IC.
Maybe not literally as close as possible, but within a couple cm anyway.
If you move yours, you’ll be left with an unsightly gap that can be filled with a couple diodes…
I’ve done this too. I can shove it on Github if anyone wants.
As its the first of a new month I went to go grab a free AllPCB order. Shows up as free then when I go to order its got the charge on there.
Popped on chat and got this: “Our monthly free prototype activities have been suspended. Only customers who have actually paid the amount within 6 months can give them free proofing coupons.”
Edit: Was going to place an order anyway, but after shipping they are way more expensive than JLC. For two boards shipped JLC comes in at $15.66 as opposed to $26 for AllPCB. Eight and a half bucks isn’t that big of a deal, but considering I can get another five batch of PCBs for the difference and still save a buck or two, that’s a hard pass for me.
I’m shocked, shocked.
With the wah, I think I’m going to graduate from golf board to proper Kosmo module with board mount pots and a panel. I’ve been having too much fun with the DIY version.
