MTN-SLdd v1.2

2 layer board of 0.48x0.45 inches (12.12x11.33 mm).

A small FET driver intended for a lot of the small twisty lights out there. Here are the differences from the other MTN-10/11/12DD drivers:

  • No copper around ground ring on component side. This makes isolating a twisty light much easier.
  • Different milled shape makes installation in a lot of the tiny twisty / clicky lights easier with less filing.

For a clicky light, if the battery tube does not touch the driver or you can’t solder to the pill, then this is not a good choice because you will have a difficult time getting a good ground.

The regular MTN-11/12DD is much better in these scenarios due to the exposed copper on the component side of the driver.

BLF SRK 7135 V2 - 46mm

by MTN.

2 layer board of 1.94x1.83 inches (49.28x46.48 mm).
Shared on November 8th, 2015 04:32.

Originally designed by Mattaus the the BLF community, I have made some updates to the design:

  • Added a single 7135 (ML) controlled by a secondary PWM channel (Pin 5)
  • Added an LDO option for 2S momentary use (LD2981 / MIC5235 / LT1761 / TS5205)
  • Changed voltage divider feed to Batt+ so that LVP with 2S+ cells can work
  • Changed “star” designations to MCU pin designations
  • Wider 7135 pads for easier soldering
  • Slightly changed location and diameter of through-hole vias for easier use
