Crumb32U4 USB-Controller Module

Crumb32U4 V1.0 is a versatile and very compact/small (just 41x18mm size!) microcontroller module with the ATmega32U4 microcontroller with integrated USB 2.0 full-speed/low-speed device module. All microcontroller signals are available on pin headers. A selectable XTAL crystal is included.

The module is shipped without preassembled pinn headers, since everybody has different preferences or requirements. A Connector Kit with a suitable set of pin headers and receptacles can be ordered optionally. The crystal is preassembled, see infosheet for details.
