Adafruit USB Host FeatherWing with MAX3421E

The Adafruit USB Host FeatherWing adds USB Host capabilities to your microcontroller projects, allowing you to connect USB devices such as keyboards, mice, and disk drives. It features the MAX3421E USB Host controller chip which uses SPI and an IRQ pin to interface with USB devices.

This Wing is compatible with TinyUSB Arduino libraries for chips like RP2040, ESP32-S2/S3, nRF52840, and SAMD21/51, and also with other USB Host libraries that support AVR, nRF52, and ESP32 platforms.

Features include a 5V 1A booster with a 500mA fuse for clean power output, and an enable pin to allow power cycling. The board comes assembled with some header pins; solder the header and plug it into any Feather mainboard to expand its capabilities.
