Original design by Mattaus. Beefed up traces and vias; added zener pad; and a few more tweaks.
- C1: 10uF 0603 Capacitor
- D1: SOD-323 Diode
- R1: 19.1k 0603 Resistor
- R2: 4.7k 0603 Resistor
- U1: attiny13a-SSH/SSU MCU
- AMC7135 Linear Regulating Chips
- Z: Optional SOD-323 4.3v Zener Diode (also replace D1 with 200 ohm 0805 resistor if this is populated)
- “3” and “4” correspond to MCU pins 3 and 2, respectively.
This driver works with any firmware with dual PWM output, such as STAR Dual-PWM by JonnyC; Pin 5 is connected to a single 7135 pad; Pin 6 is connected to 7 7135 pads.

Simple 16-bit ISA to pin header adapter. Can also supply -5V, if required.
