M5Stack USB Host Module with MAX3421E

The USB Host Module from M5Stack adds a USB-A port to the M5Stack Core. The MAX3421E chip is controlled via SPI and works as a USB host or as a USB device. This allows a mouse or keyboard to be connected, for example.

Important: According to M5Stack, this module is not compatible with the Core2 and CoreS3. For these Cores there is the M5Stack USB Module MAX3421E v1.2 with DIP switches for Basic, Core2 and CoreS3.
