Minerva O gauge Class 14 - adding stay-alive

Kit: SuperCap 17000uF

Fabulous model from Minerva of the Teddy bear. This one has a Zimo MX645PluX22 sound decoder and speaker fitted at the factory, so we just needed to added stay-alive, which there is plenty of room for a SuperCap. Connection points in the diagrams below for MX645 and also the newer MS450.

Wrap the SuperCap in kapton tape and secure with BlackTack underneath the PCB.
