From the project

A simple DC regulator for flexible electronics prototyping.

A simple adjustable DC voltage regulator built for powering, monitoring, and protecting a variety of electronics prototyping projects.

- Initial release. Functionally the same.

- Supports only one power source at a time (DC input via banana plugs, spade connectors, jack, or USB-A). - LM317 limited to 1.5A. Internal power busses wired with 16 AWG for ampacity. - Adjustable voltage output for a broad range of applications.
