PIMETA Headphone Amplifier

It's a PPA-Inspired META42 successor. It's about the same size as the META42 board, but the topology is closer to that of the PPA.

The PIMETA board is designed with single-voltage supplies in mind, and in this case, you need the TLE2426. However, you can instead use a true dual-voltage power supply, allowing you to leave out the TLE2426. V+ and V- from the power supply go to the outer + and - pad pair, and GND from the power supply goes to the OUT pin of the TLE2426 position.
