Ottercast/OtterCastAmp
OtterCastAmp is an open-source WiFi Speaker amplifier, based on a Sochip S3 SoC. Powered by any USB PD adapter for up to 100W of music.

The DMP4015SSS is a MOSFET made by TECH PUBLIC in a SOP-8 package with 8 pins. -55℃~+150℃ 1 P-Channel 12A 18mΩ@10V 2.5V 2.5W 2.8nF 220pF 40V 40nC@20V SOP-8 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PMOS_1S_2S_3S_4G_5D_6D_7D_8D, from PCBKit's generic symbols) and its footprint (Package_SO:SOP-8_3.76x4.96mm_P1.27mm, from KiCad's library), ready for a KiCad board. 6,516 are in stock at JLCPCB (part C5197355). 1 open-source board in 1 repository on GitHub use it.
