[WIP] 17mm DD+single-7135 driver / single sided / Dual-PWM

[wight]

@Tom E

Ohhh - think Dale’s post on v013 was in the humongous BLF Kronos X6/X5 thread, long buried by 100’s of posts by now, only hours later .

Thanks wight for the info! I do like the expansion outer tabs for the springs - definitely useful.

In the last couple days I used one of you 009’s with a ATTiny85, pins bent in, and piggybacked to the stock driver. The stock driver had a blue LED on it that shines thru the rubber around an e-switch. So, I left the LED and resistor (also switch and charger connector) on the stock driver/contact board, and wired MCU pin #3 to the resistor of the LED. So far it’s working great! Got some more tweaks to make to the Narsil firmware to fix bugs, and have it handle low battery alerts, but it’s working real nice. Even with the wire on pin #3, I can still clip the MCU for programming because the bent pins elevate the MCU up. Would much rather have a pad for pin #3 on the component side for doing this, but you probably don’t have space.

For me, using pin #3 as a jumper doesn’t help - I got lots of configuration options in the UI of Narsil.

• Ah, thanks. I was able to find it based on that. The post you were referring to is #4869 and shows a “real” v13 from OSH Park. The discussion going on around/before that post seems to cover a lot of ground we’ve already covered. I think Sharpie had the Gerber viewer set with a layer missing. Some points are still valid, even if they’ve been touched on before.
• I agree with you - the star doesn’t do much for me except look cool. I don’t use stars.
• Maybe later I’ll scoot things around on a 20mm board and break out the extra pins. I prefer to break them out when I can, but as you’ve mentioned space is at a premium.
• Please be sure to report back on your results with those spring pads.
