Thatâs why I prefer Biscotti driver⌠3A regulated output and customizable interface.
Simonâs drivers became my first choice some months ago for any simple light (S2+, C8, any tail-click li-ion only lightâŚ)
Maybe you know then if the biscotti drivers that Simon sells at this moment have the corrected firmware? I have been waiting for a year now for confirmation of that.
Jos, do you have any info on what should be corrected?
I bought one driver with Biscotti from bg last year for an S2+, the UI is much better then the 3/5 mode and still regulated
The first batch of biscotti drivers had something wrong in the firmware (a âfuse settingâ), making the PWM frequency twice too high, and also the timings of any events in the UI. Getting into program mode was difficult, and maybe the modes were affected too, canât remember. Annoyingly, because superficially there seems nothing wrong, Simon kept selling those drivers and putting them in his lights. Even the desert tan S2+ that came out half a year later have (sometimes?) drivers with wrong firmware. He may even never corrected the firmware? I donât know because it canât be found on Simonâs site and no one ever took notice again. I just know that I really want a stash of biscotti drivers but only if it has the corrected firmware (I can not re-flash drivers).
The ones I bought were easy to use, all of them were 8*7135 if that changes anything.
No problem getting in config mode, nor setting the correct group.
I didnât see any complain about them, so I would guess that itâs gone now ?
But Simon sells biscotti drivers with less chips too, there may be some left of those with wrong firmware. I can get answers in the form of âprobablyâ and âmine seems fine, bought then and thenâ, but a year ago i bought 12 drivers, all with wrong firmware, and I would really like to be certain if I buy 10+ drivers again.
I just looked on Simonâs site,and there is a 7135x3,4,6 or 8 driver with ânew firmwareâ.It has the ui map,so i presume it is Biscotti.Convoy .Hope itâs the right one.
It is ânew firmwareâ as in: now biscotti firmware vs formerly the 3/5 mode firmware. But it does not mention the fixed vs non-fixed biscotti (because that would imply that there was a non-fixed biscotti for sale before which does not look good as a seller). I think that Simon decided that the firmware with wrong fuse-settings was good enough, and at that point it is essential not to mention anything wrong.
I bought them from BG (8x 7135) and had to wait several times when they were out of stock.
How do i figure out if i have one with the wrong software fuse?
I donât think itâs just a simple matter of wrong fuses in the firmware. It think itâs a hardware issue. As a result, TKâs original Biscotti and its derivatives no longer work correctly with the driver. Itâs a mess. Even if you order the ânew firmwareâ or red Biscotti drivers straight from Convoy Store, thereâs no guarantee the driver will work correctly, unless maybe itâs the clear C8 from old stocks.
