Attiny45V microcontroller. It has more memory, which leaves more space for me to do firmware customisation. Unless you intend to change firmware, it’s useless for you.

Attiny 45V more memory than the 25V
V is some sort of low voltage enhanced version that is needed for OTSM to work

Thanks for that information. I won’t likely be changing the firmware so not for me.

You will have to choose between having low voltage protection and no temperature stepdown (narsil v1.2) or

temperature stepdown, but no LVP (narsil v1.4).

I went with LVP and let my hand control the temperature.

Yeah i agree, LVP much more crucial for me too.
As far as i understand with 1.2 i loose the ability to add a led to the e-switch to have it show me voltage readouts. But i still could add a led there just as a locator, did i get that right?
Also i could flash the 1.2 with 1.5 when it is ready if it is not by the time of sending out batch 3, correct?

My order should be something like 30mm, Narsil 1.2 with LVP, and 2S LDO if i got everything right.
Btw, can the tactical 100% blast on the rear switch be removed? i would prefer to use the clicky just as lockout

Your right, you can’t use the indicator output with v1.2, but you don’t really need it. When you triple click, the main led will blink out your voltage. Plus you can use the power output pad to make the side switch light up when the tail switch is on (locator).

If you know how to flash it, then sure, you could upgrade to version 1.5 when it is ready. I don’t know how to do that.

The tactical rear switch is written in the code so it can’t be turned off. It would require a reflash to get rid of it. I have the tactical on my L6, but find its not as practical as I thought it would be. It’s so easy to click on and off with the side switch that I find myself not wanting the tactical option. This second driver I’m ordering will be programmed to do nothing when the rear switch is activated. I will know the rear switch is on because I plan to have the side switch light up on my new light as well.

you can choose how the light reacts to the rear switch
tactical=turbo
2B= 2 low blinks to aknowledge the Light is ready
NO=No light by the main LED

2B seems like the best option to me.
Btw, in group mode what are the spacings of the different levels?
And is there a posibility to choose custom output levels for a certain group?

Edit:
Oh, and will there be a version with both LVP and Temp protection for 2S in the near future ? Is it a hardware or software limitation at the moment?

depends when Tom E will oficially release NarsilM

Customizing mode groups is no problem

So if i get the 1.2 version driver now, and later Tom releases NarsilM, i could flash NarsilM and get the Temp protection too, is that correct?
Or some hardware modding would be required too, to get both LVP and Temp protesction with NarsilM?

if the NarsilM is set to LVP on Pin 7 it will work with same hardware as v1.2

I think what he’s asking is if you will have to switch between pin 7 being for LVP or for temperature.

Wasn’t it hardware limited that there were not enough pins to do both at the same time?

Narsil v1.3 and v1.4 switched from voltage divider to internal voltage reference to add the indicator LED
Also temperature protection was added

Hardware limitation is only to do indicator or 2S LVP in next Narsil version

To be more precise, i was asking if i now get the 1.2 2S Narsil driver with LVP on PIN 7 and then Tom’s NarsilM comes out with LVP set on PIN7, i flash it on the driver.
Will i then have both at same time 2S LVP + Temp Protection ?
Or it still will be a choice between 2S LVP or Temp Protection?

Hope its clearer what im asking.

NarsilM has of course temp protection avaialble, no external pin needed for it

when flashing NarsilM pin7 must be set to external voltage reference then compile the hex

if done right you can simply flash NarsilM over a v1.2 and it works

Been there, done that. That is a lot more work then it looks like (and it looks like a lot).

What do you guys use to inspect them, a magnifying glass?

I’ve found that my phone camera set to 5x zoom and a small flashlight makes for a very handy video microscope kind of thing.

If I had to do a lot of drivers I would get a tiny turntable so I could rotate each driver while holding the camera and light fairly steady. It’s so much easier on my eyes. Thumbs Up

I always wear a magnifying headset when soldering these types of things, no way would I try to do that with the naked eye on a regular basis.

I have a much stronger 10X magnifier for detail inspections if I need it.

I got mine at harbor freight many years ago, they have a different one now. It should still work but only has the extra magnifier over 1 eye instead of both like mine. They are sell them on amazon as well.

Soldering smd stuff for me is like firing a sniper rifle. I set up the shot, hold my breath and gently make quick contact to the joint. Then I breath and check my work. Lol

It is much much easier when you can see what you are doing. I really want a big desktop magnifier or better yet a microscope but they are a weee bit more then the $5 I spent on the headset, so I will live.

for inspecting this tiny stuff enough light is more important than magnification

I dont need magnifier to check those boards, if there is a bridge I see it under my 1000 Lumens desktop lamp which has a narrow beam

This is why I don’t even bother trying to use an iron for smd anymore. Solder paste + hot air is much easier.
