+ *  19    PB0   (none)
+ *  20    PA7   e-switch (PCINT7)
+ *      ADC12   thermal sensor
+ *
+ * Main LED power uses one pin to turn the Opamp on/off,
+ * and one pin to control Opamp power level.
+ * Main brightness control uses the power level pin, with 4 kHz 10-bit PWM.
+ * The on/off pin is only used to turn the main LED on and off,
+ * not to change brightness.
+ * Some models also have a direct-drive FET for turbo.
