This switch uses an ATTiny85 micro-processor to control the on and off cycle of a LevelMatePro, Kohree RV Leveler, and Rhino Storm Leveler Pro bluetooth enabled levelers. It requires a trigger, which can be any 12v source, including the Backup pin of the trailer’s 7-pin connector, or any other pin such as the right-left turn or tail lights. It can also use a 433 Mhz wireless relay for remote operation. Simply, if it is 12V, it will trigger the Leveler Controller.

The controller outputs 3.3VDC for use by the levelers. However, due to the flexibility of the controller, any source from 3.3V to 12V can be used for the output power supply. That means you could use this controller to turn on a backup camera for example.

This is a Leveler Controller that will power and automatically and turn on/turn off a LogicBlue LevelMatePro, Rhino Storm LevelerPro, or Kohree RV Leveler. All of these levelers are bluetooth controlled, and they use 3V button cells for power. The Leveler Controller provides 3V power from the RV’s battery system to alleviate having to change out button cells frequently..

The MCS-3C Leveler Controller consists of a power supply, opto-isolated trigger circuit, and ATTiny85 microcontroller to control the behavior of the controller. Upon the receipt of a trigger signal, the controller will turn on the leveler in one of 5 different methods - set by a mode switch on the pcb.

Rev B cosmetic changes. Order 2 oz copper if you need the 1A version, or 1 oz if you need the 500mA version.
