Board Applications
Robotics.
Portable and wearable electronics.
Low or high power applications.
Battery powered electronics.
Custom built small compute devices.
Features
Dual output, switching and linear.
SIC431 based switching side.
End-user choice of linear regulator.
Tuneable or programmable switching side voltage output via potentiometer or bypass jumper.
Daisy-chain or fully separate supply to linear regulator configured by solderable jumpers.
Enable/Disable pin for switching side with optional pull up/down resistor pads.
VReady pin from switching side for sensitive electronics.
Warning
Higher Amperage draw, causes the board to reach temperatures not suitable for being touched by the user. Therefore an enclosure should be used to prevent the board from being touched or sufficient active or passive heatsink applied to reduce the temperature, in this case.
Important Notes
This kit is recommended for those who are comfortable with soldering as some assembly is required. It is also recommended to have a basic electronics understanding.
Make sure to read the documentation carefully as this product is not plug and play.
Make sure to use the correct wire gauge for the power you are drawing.
