In short… it is 12Watt HDR buck driver with 95% efficiency for Shillhunt H0x or Convoy H1 headlamps or any other lights with 21mm e-switch driver. It have pads for Attiny1616 flashing and aux-led to shine though TIR optics. It was designed according our hardware master thefreeman schematics and help, so I am grateful to him for that.
UI ? Thanks to our software guru Toykeeper who coded UI constructor, any UI can be made, but for now, it can run simple and intuitive ZigZag UI ZigZag_V1.3.pdf (66.2 KB) ZigZag_V.1.3.3.hex (18.6 KB) ZigZag_V1.3.3_batch2.hex (18.6 KB)

Ikr?! Convoy teased the host of a dual emitter headlamp. Looks lot better than their previous offerings. I will wait for it and if it’s not good, or the UI still suck, I will have to plunge to get a premium one.
Either way, I’m done with unregulated hotrods on your head which does 1000 lm for 30 seconds.
I think the upcoming Convoy H4 is inspired by the Sofirn HS20, which is a very nice headlight that I use.
I’m waiting for the H4 (or whatever it’ll be called) as well.
Flood + throw can be quite useful. Indoor and close up work with flood and outdoor with throw. Just don’t use 21700 battery because it’s way too heavy.
