XL5430 ±5/12/15V Positive To Negative Dual Voltage Power Supply Module TPS5430

This little module takes a positive input and gives you both positive and negative outputs—handy for powering op-amps, audio gear, or test circuits.

Based on the TPS5430 chip, it can do ±5V, ±12V, or ±15V depending on how you set it up.

It's brand new and unbranded, but the design is pretty standard.

Just wire it in and you've got a bipolar supply from a single positive source.
