I also got 3 of those 105d drivers instead of regular ones, and i was refunded, in the opened ticked a guy assued me there those shoudlnt be even in the store
And mine didnt have memory too
From now on will order 4 mode ones
The stars on this version, while functional, are mainly for show. R3/R4/R5 are where you easily bridge each star to GND. A pick-n-place machine or assembly worker can easily place a zero-ohm jumper across those pads.
stars for bridging throw some 000 resistors on the pads, if you look close the star is connected to one side of the resistor pad, the other side is connected to ground
Most definitely odd, but interesting on the new revisions of the 105 *7135 type drivers
8x AMC7135 generic driver with star-selectable mode groups:
A couple of interesting observations; the spring is much larger, making it much more useful than the factory spring on the 105c. Also, the above pic from FT doesn't show it, but the stars are printed in two pieces, so you just bridge the two halves to make your mode selection. I haven't installed one yet to check how the PWM, fit, and mode groups work out.
