Hi Jason i might have 
by looking at the picture that cable+resistor is use for side button LED is that correct?
Yes, it goes right over the R2 label, on top of the Texas picture. This is the positive side. It should also be a 47 2 resistor, meaning 2 zeros = 4700 ohm.
what is the different between side-button led and indicator led?
Well indicator led is the special output from the driver which can do different fancy things. Like turning off, becoming a beacon, blinking voltage, etcâŚ
A side button led can be anything. For instance, I hooked my side button led to driver power, so I know when the rear switch is on.
Do you mean âlighted side switchâ that Lexel drew on his diagram? Thatâs just a power source letting you know the driver has power. Itâs a bit redundant, but no big deal. It doesnât do anything fancy.
got it now. thanks Jason.
in your case the resistor was soldered to the Bleeder positive pad for lighted sideswitch, must broke off during transoprt
Hey Lexel, I just saw your post in the Astrolux MF-01 GB thread. Are you offering TA drivers for the MF-01 in this sale? If so, how much would they cost?
yes i ask for lighted side switch in the original order.
so i just soldered the cable with the 472 resistor to R1 in order to use indicator led?
2S LVP drivers have no indicator LED as the MCU pin is used for voltage reference
oh i forgot about that. :person_facepalming:
thanks Lexel.
Iâm interested in 2 for convoy L6, NarsilM 2S FET+1 no LVP
I hope I understand right, unfortunately I do not speak English
FET+1 is possible I need to figure out how to change the channels config to match the same pinout for FET+1 to triple channel boards
It will take a little as I have atm no more 30mm boards but I have ordered more that should arrive soon
Before you try to redesign the driver, are you sure this customer really needs fet+1?
Are they trying to loose the lvp to gain the indicator led? If so, then itâs not really necessary. A simple âpower onâ lighted side switch is just fine. Lvp on a 2S light is pretty important.
Sorry Iâm wrong with FET+1, I need 2 30mm driver with NarsilM and lighted side switch.
I think thatâs just like my L6. Iâve got instructions and pictures how to add the switch ledâs and get a clear cover from convoy. You can power the switch lights with regular power from the driver positive and negative or you can use the little pads on the driver. The âindicatorâ function is not really needed. Itâs better to just know if the rear switch is on or off. Plus when its on, it helps you find the light and find the switch to push.
Fet+1 is a 2 channel design. This Texas Avenger driver is a more efficient 3 channel. I think its FET+8+1? Itâs better. 
Thanks, I want to replace the current MTN FET driver mainly for ramp mode and I find the side switch illuminated very comfortable
Basically cost is the same as the Q8 driver
just I need to get 3 boards at a time from Oshpark so it would make sense I get at least 2 orders for this size
you may ask in MF01 topic if he sells one of the 3 boards he ordered, he got parts and skill to build em
30mm 2S NarsilM driver with lighted sideswitch is not a problem, I have build a lot of them and people are happy with it
of course for lights with mechanical tailswitch the lighted sideswitch with a bleeder is a good option,
just for any 2S NarsilM you have to choose if you prefer the MCU with intelligent indicator LED or LVP on pin 7,
even 2 LEDs in sideswitch are possible
Thanks Lexel, 30 mm 2S NarsilM driver with illuminated sidewitch (2 Led)is exactly what I need.
sorry for my chaos
Maybe , as suggested by JasonWW , should I add FET + 8 + 1? But I do not know if this configuration it is necessary , only to have the firefly or moon level, that I do not care about.
For middle modes the 9 AMCs are good as it is a regulated output, constant brightness, less or no PWM and more efficient than FET
All the drivers Lexel is making are triple channel.
