In the description of their 1.4A 7135 driver at Fastech they say you can delete strive modes by shorting a pin to ground
I think the “short D1 to Vdd” is wrong as D1 is just the reverse polarity diode. I think what your supposed to do is short pin 3 to pin 4(gnd) on the IC. This has the same effect the stars on a 105C. I tried this on a 4x 7135 driver from international Outdoor that had [these instructions](http://www.intl-outdoor.com/amc71354-5mode-circuit-board-nanjg-101aka1-p-254.html(see) near bottom) so I’m thinking it’s the same deal maybe? Anyone have these Fastech boards to try out? The one sided multi mode boards don’t have stars so it would be nice to have a way if eliminating the extra strobe modes. I’ll try it on a DX 17- mode,3- group driver next. I like having those modes for some lights but others are a pita to switch if you fall into a blinky by accident.
I’ve done the same with the intloutdoor driver, surely it’ll depend on the ic?.
Your right, of course. The Fastech must be a typo though. I just tried on a DX board with a wire to the ground ring shorting each of the output pins on the IC in succession and all it did was change the initial mode. I had just wondered if it was a hardware issue common to Attiny 13A driver boards.
All of the nanjg drivers with tha ATINY 13A microcontroller thingy do the same thing. Connecting pins 3 and 4 with a bit of solder sets it to L, M, H output mode. Not all of the drivers have the four star options but, the stars are connected to the pins on the microcontroller and if you connect the pins accordingly (regardless of weather stars are there or not,) the outputs of the driver changes. Sorry, I did check at some point which star connects to which pin but that info was lost since I only use the L,M,H group.
