Tca9548apwr is an open source PCB design by atopile: a 2-layer, 10.5 × 12.4 mm board with 20 components (12 distinct parts). It is built around the C2913205.

The TCA9548APWR is an I2C multiplexer that allows you to connect up to 8 I2C devices with the same address to a single I2C bus. Its kind of weird to need this, but it's a thing.
