Yes, this: https://budgetlightforum.com/t/-/31102
I've built a couple with my custom e-switch firmware, based on the latest version from JohnnyC, STAR_Momentary (http://bazaar.launchpad.net/~toykeeper/flashlight-firmware/trunk/files/head:/JonnyC/STAR/STAR_momentary/). It has full support for the two PWM outputs. Recently modded a UF F35 e-switch light, a Yezl Y3, and now I'm working on a ZY-T11 clone. I got amazing #'s on the F35 and Y3 in a neutral tint, so expecting the same for the very pocketable ZY-T11 clone - it will have a MaxToch 25mm MCPCB screwed down, 20 AWG wires with the LED+ direct connected to the spring from the LED via holes drilled thru the stock driver (stripped) and hole drilled thru the LED+ pad on the HYBRID board. The ZY-T11 clones from BangGood is a great deal for what you getting, and really nice mod host. Like the lockout feature of the anodized thread tailcap, very compact size, nice size reflector for some throw, can take a big MCPCB, excellent reflector for wire soldering clearances, etc. The quality of the anodizing is fair (not good) and you play the lottery on what condition it will be in, but I lucked out on the 3 I've gotten.
