- Refine input voltages.
- 1A fuse.
- Labels for V/A/W monitoring units.
- USB-A VBUS blocking diode.
- 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.
- Implement a switchable input selector for safer handling of multiple power sources.
- Add a USB-A VBUS passthrough to bypass the regulator when voltage adjustment isn’t needed.
- Boost current capacity using NPN power transistors in an emitter-follower configuration.
