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 AP6236 is a wiFi Module made by AMPAK Tech in a SMD,12x12mm package with 47 pins. -30℃~+65℃ -87dBm 14dBm 2.4GHz 3.3V Bluetooth4.2、IEEE802.11b/g/n Integrated Bluetooth function UART、SDIO、PCM SMD,12x12mm WiFi Modules ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:AP6236, from EasyEDA) and its footprint (EasyEDA_Cloud:COMM-SMD_AP6236, from EasyEDA), ready for a KiCad board. 498 are in stock at JLCPCB (part C2908817). 3 open-source boards in 3 repositories on GitHub use it.

The symbol is EasyEDA_Cloud:AP6236 and the footprint EasyEDA_Cloud:COMM-SMD_AP6236, both drawn on this page. PCBKit places them on a board for you when you design with it.
SMD,12x12mm, with 47 pins. Its footprint is drawn on this page.
AMPAK Tech publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C2908817, with 498 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the ESP32-WROOM-32E-N4 by Espressif Systems, the ESP-12F(ESP8266MOD) by Ai-Thinker, the ESP32-WROOM-32 by Espressif Systems and the ESP32-WROOM-32E-N16 by Espressif Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.
