As promised…preliminary release of a Nanjg 105C equivalent compatible $7 headlight driver
2 layer board of 1.5x1 inches (38x25mm). $7.40 for three
Top
Bottom
R3 is a 100 ohm 0805
Everything else is stock Nanjg 105C, with Star Momentary Werners UI, you can have 5 levels (heck you could have 10 if you wanted) round robin with this
SW is tied into pin 2 for momentary driver support
I haven’t released it because the copper pour went all stupid under the 7135’s…don’t know how to fix it but it should work, the led on the back will light up when the light on the front comes on…it will be PWM driven as well. - edit - went back and fixed alot of the goof on the copper pour, added a few extra vias, doubled the power trace width, and it cleaned it up - edit -
I measured the board
37.87mm wide, 25.17 tall
2mm holes
2 bottom holes are 5.5mm from the sides and 2mm from the bottom edge
top is centered and 1.25mm from the top edge
If anyone is interested I would like one of the Eagle guru’s to review my work, before I share
