EZ Servo - High Voltage Servo Driver

Turn an unused EZ stepper driver socket on your BTT MMB into a high voltage (6.0V/8.4V) servo output for running high voltage servos with higher torque.

 

DC-DC voltage converter board for use with EZ stepper driver sockets on the BTT MMB control board


TPS5430DDA Step-down converter configured for 6.0V or 8.4V output, up to 3A
Pin header with servo output
Optionally, use stepper motor output on controller board as servo output (1B: GND, 2B: VCC, 1A: SIG)


Parts that need to be sourced if assembled by JLC:
  - 1-2x 3-Pin Headers <![CDATA[]]>Right Angle Header 2.54mm Pitch<![CDATA[]]> or similar 
  - Output Inductor 47uH <![CDATA[]]>Bourns SRP7050WA-470M<![CDATA[]]>
