  • good as long as it worked

    posted by tonighx

    - very small board- cheap- wide range of input voltage- keeps a minimal light on even when the batteries are extremely low, going into a kind of "low-strobe" mode
    I soldered two cables to the contacts on the back to connect it into a DYI bike light with sku.44306 and sku.5602
    I would buy this again for other DYI projectsIt would be nice to have better information on which driver to use for which emitter
  • 70% Efficiency buck Driver

    posted by amelyman

    27,9 Watts power from source at High mode
    So, looks exactly for SST-90 LED...
    Probably I hame made some mistake thru measuring and the Efficiency is higher...
    I measured with UNIT UT-70A Multimeter the linear voltage and linear current. As I know, it is not exactly correct (LED power is not "Linear")
    Really powerful driver. So, it has 5 modes - 28 watts, 14 watts, 8 watts from the Source and fast strobe and S.O.S. modes.
  • When you need local storage

    posted by kirovclass

    Simple daughterboard that can help you to provide your Arduino project with a local non-volatile storage.PCB design seems very clean, nothing to complain about it.
    An improvement could be to ship it with an optional connector that allows it to mount the board horizontally.
    There are no much choices when there is a need to store data locally on a Arduino project, and for the little price, it's good to have one of these in the toolbox.
  • LED Driver Circuit Board for Flashlight

    posted by Pahentij

    All as described. Good driver. A lot of configured modes. Very good choice for single Li-ion torches.The driver uses an Amel ATtiny13a microprocessor and it can be custom programmed! Very reliable driver, great for DIY project or repair your flashlightFast shipping and good packing.
    Nothing to say.
    Good for modding flashlight on a cree xm-l and similar LEDs. It's a good way to change the mode options in your light.Highly recommend!
  • 3*7135 chips

    7135 chipsRegulatedMemoryReal output advertised
    This regulator drive out fairly steadily 1.4 amps. in max. mode.Exactly: 1.35 in high mode, 0.4 in middle, 0.6 in low (fluctuating in sos and fast strobe modes).I have put it, working together with a 16 mm alu base Cree R5 led in my Trustfire TR-801, and it bright now 25%-30% more than the original Cree Q5 led, giving a really flood light!According Cree data sheets, Cree R5 can hold up 1,5 mA, so this regulated circuit is perfect to this led. Other drivers that can only drive up 1000 Ma, will give 25% less light tan this.
    I recommend it
