SymmPower Converter - Low Noise +/- 5V Power Source

The SymmPower Converter is a compact, open-source power module that converts a single positive DC input (3.3V to 5V) into ±5V ultra low noise outputs. It’s an ideal solution for powering bipolar analog systems such as op amp circuits, ADCs, DACs, and other precision signal chains where clean rails are essential. In addition to its regulated ±5V outputs, the converter also provides intermediate rails at approximately +6.2V and -6.2V, which can the user can also access. The SymmPower Converter is available in two versions: Screw Terminal Version: accepts input power via a 2-position 2.54 mm screw terminal USB-C Version: accepts input power via a standard USB-C connector Both versions also include: 2.54 mm pin headers for input and output connectivity Dual 2-position screw terminals for accessing the ±5V outputs Whether you're powering sensitive analog circuitry, testing a new precision design, or building a portable data acquisition system, the SymmPower Converter gives you a clean, reliable, and easy-to-integrate bipolar power solution — all open source and ready to drop into your next project.
