the thing has a USB port
surely that is how the firmware gets loaded
has anyone tried to reprogram it?
i hate the UI, needs to be more like BLF A6 or astrolux S1
also the light levels are awful - the first one is too dim for anything, then the next one is too bright, and the others are too bright and too close together
Nope, it´s just a charging port! You cannot “hack” it or install a different firmware like Bistro or Toykepper A6.
You are right, the low mode after moonlight it too bright. You cannot change this, even in PRO mode.
If you can´t live with that, get a different light instead.
In this U11 teardown you can see a chip marked “T44 AHB”. That should be an Atmel ATtiny44A.
It has a different footprint than the Attiny25/45/85s usually used here.
If you find a way to connect the required pins (a four-sides QFN/MLF/VQFN clip if it exists may work or not) it should be as programmable as the other microcontrollers. (I guess the chip is programmed before soldered to the board.)
You just have to reverse engineer what pin does what to adjust your firmware of choice accordingly.
