MX645P22PluX22 direct plug-in version

The MX645 sound decoder from Zimo is perhaps the industry leader in OO and small O gauge, packed with all the features you have come to expect from Zimo, plus 10 AUX function outputs for lighting, smoke generators, auto-couplings etc., and 'smart stop' energy storage facilities built-in (just add an external capacitor to take advantage).

Supplied with the MX645 is a 'sample' electrolytic capacitor (normally a small 16V 470uF) - worth connecting, but also worth considering an upgrade to 1000uF if you have space in your model, or even better, a SuperCap (6800uF or 17000uF).
