USB On-The-Go on the ESP32-S3 ยท Daniel Mangum

| The ESP32-S3 is a popular microcontroller (MCU) for a variety of reasons, such as its support for external pseudostatic RAM (PSRAM). One of its lesser known features is its Universal Serial Bus (USB) On-The-Go (OTG) controller. The previously released ESP32-S2, as well as the new ESP32-P4, also have USB OTG support, with the latter having two controllers. USB OTG devices can act as a device or as a host. This is a popular feature for smartphones, which, when attached to a laptop or desktop should act as a device, but may want to act as a host for some peripherals, such as a keyboard, that may be attached to it.
