Changes by last author:

Changed:
* gate resistor 1k (max 2k7)
* gate resistor 1k (max 2k7)
Changed:
* Output= Drain, with flyback diode (SMB or BY399), diode cathode = flyback return (EC36/23)
* Output= Drain, with flyback diode (SMB or BY399), diode cathode = flyback return (EC36/23) (or +12V)
Added:
Possibly gate controlled from v3.8 Extra Output 5/6 :

Previously (v3.7 had) onboard provision for DPAK FETs driven from these signals (drain connected to EC18/pin6 and EC18/pin12), but flyback diode was still needed.
