Planting plan

Rotator (DB15 female) and power inputs connector

Phase jumper (5+6 CON1) change relay function between DC (change phase voltage) and AC (change direction).

Pin 3 in CON1 - input 5V stabilized voltage from power board This pin may be connected with pin4 CON1, then the voltage measurement uses a common 5V voltage from the power supply module.

The entire module can be powered from USB only, but there is a voltage drop, it is better to use an external source, or a DC/DC converter.
