Been looking this over but can't see pin #2 connected to a pad for the switch - did you run out of space for it?

I know there's not much room on a 15 mm, to say the least.

DEL has a good write up on his 17 mm FET+1 here. He writes these are the mandatory parts:

  • C1 10 uF
  • D1 diode
  • R3 100K ohm to eliminate unintentional flashing during mode changes
  • R5 4.7 ohm to eliminate unintentional Vcc boosting during PWM

C2 and the R4 47K ohm resistors can be eliminated

Right, no space for pad , just connect straight to pin. Why not? LOL

For 15mm, we make compromises Smile
Might make it a pain to re-flash later

I tried to (quick) read the entire post to find FW3A switch board or contact board but couldn’t find any.
Is it still a rare part?

Nice! I'm attempting to order from PCBWay - $5 + $8 e-packet shipping for qty 5, total $13. Decent price, no rush.

Looks like PCBWay has to do an approval on the order first. Thinking they will take PP. They also offer a ton of options - hoping the defaults are good for us.

Yea, I see that now - thought it didn't work before, but I was tweaking settings.

Unfortunately after the review, they raised the price from $5 to $15. Dunno - I'm re-submitting with qty 10, maybe I made a mistake before.

Ok, this time with qty 10, the price stayed the same smile. Looks like they give you choice of colors for the solder mask and silkscreen, but won't take the chance of changing anything now...

 

Transaction went thru! Also added a $5 coupon, figure it was for first time order, so total cost with e-packet shipping was $9, including a $1 PP fee they added.

 

Not Bad! smilecool
