Hello,
I recently finished my last holiday project. This is the driver for the D4V2 flashlight. It's my 4th PCB.
It features:
supporting AUX RGB, with AUX button (titanium version)
configuration 1 amc+7amc+fet (like e.g. in fw3a)
hole in the board for the main diode cable
thicker printed circuit paths
program pins compatible with Emisar
Design isn't revolutionary, but finally I have a cool D4V2.

What makes this cool vs standard d4v2?
Same question as above. The standard D4v2 driver is additionally pwm less.
I don’t want to criticize your construction, it’s nice that you built it yourself, but I wonder about the purpose of this project.

The standard D4V2 driver uses PWM for both 7135 and FET.
The new 5A or 7.5A constant current driver, which you can ask Hank to install in a D4V2, only uses PWM for FET.

Wallkiller’s driver is better.
1AMC + 7AMC + FET vs D4V2 driver (only 1AMC + FET).
3 channels vs 2 channels.
Good job Wallkiller

It’s an upgrade over the standard D4V2 driver. It is regulated up to (1+7) * 350 mA = 2.8A with PWM.
However, Hank’s new constant current driver is regulated up to 7.5A and without PWM.
I think it's great! There's nothing better than putting your own skills into building something!

You mean this driver? Haha
