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

CV fixed gain, variable offset
This started out as an educational schematic to show how to take a Control Voltage that ranges from 2.2V to 10V, and expand it to cover 0V to 10V. The differential amplifier gain is set by R2/R1 and R4/R3, where the resistors should match. The trim resistor allows 0V to be dialed in.
