Really nice boards But tbh a lot of this goes over my head!
I disassembled my D4 recently to flash Anduril and found it very tricky to work with given the extremely limited space. I’m not sure I’ll have the skills or patience to take it apart again to add the aux cables. I really like the aux leds in my D4S though so I could be tempted.
The D1 TIR looks interesting as well. Do you have any more info on that?
Any plans to make one for the imminent release of the FW3A?
Lexel - I's like to order a couple, maybe more, of these boards. I need one for my ROT66 (early version no AUX LED's), a D4, another quad, possibly an MF01, and possibly when you get the D1 ready. How does this work? pm you?
It is not easy to install. The driver is hardly pressed in and there is verry less space for wires and soldering.
You will need a tiny wire for battery- on the aux-board. Battery+ is the same as LED+.
You could also flash Anduril for D4 with Aux support. D4S might work, but it’s not ideal as the part for the thermal regulation is made for a bigger part. Also the level mixing is off, as the D4S has more AMCs.
So if I understand correctly, the LDO on the D4 TIR board causes it to have only one level of light? But if you took out the LDO then you could have low/high? I’ve never used aux lights before, so I’m basing it off of the H03 lexel driver with anduril, the light under the button has a few modes, high, low, flashing, off. Would this be the same with the stock D4 TIR board? Or would the LDO need removed? What are the implications of doing this?
I know I will need to flash the D4S firmware, or D4 anduril with the aux code added. But the LDO has confused me.
Sorry for all the questions, I want to learn, trying to understand.
Yes if you want high low then the LDO can be replaced with a resisor, which fits 0603 to get between the pads or build with resistors based on 3.7 not 2.8V
The LDO is to stabilize the current while battery voltage drops
I am very interested in modding my D4 with an aux board.
I want the aux LEDs to act as a locator light, with a brightness roughly comparable to a large tritium vial. They shouldn’t light up a dark room.
I guess your “0.15mA” brightness level is most suitable for that?
Can I order a D4 board with a trimmer installed instead of an LDO so I can adjust current without soldering?
If yes, what is the approximate adjustment range for the “0.3mA” and “0.15mA” levels?
Problem with D4 board is it has no space for a regular 3x3mm trimmer
2x2mm trimmers may be possible to fit would need a new design and are pretty expensive so I never invested in that build
It is possible to replace the LDO carefully soldering with a resistor and you can use high/low feature with D4S Firmware to get on low tritium brightness
or just build at very low constant current with LDO
