Atmel/Microchip SAM C21 microcontroller module with USB UART and dual CAN bus.

Sammy-C21 V1.0 SAM C21 CAN Module

Sammy-C21 V1.0 - Atmel/Microchip SAM C21 microcontroller module with USB UART and dual CAN bus.


Sammy-C21 V1.0 is a versatile and very compact/small (just 18x38mm size!) microcontroller board with the SAMC21G18A microcontroller, CP2102 USB UART converter and two CAN2.0/CAN-FD standard compatible CAN bus transceiver. All relevant controller signals are available on pin headers. 16MHz XTAL and 32768Hz TOSC watch crystal are included.

The Atmel/Microchip SAM C series of 5V Cortex M0+ devices is designed for industrial and commercial applications in noisy environments. These products feature robust communications peripherals including the SERCOM module and CAN-FD, along with advanced motor control peripherals, and the Peripheral Touch Control (PTC) for developing robust user interfaces.

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

New: The Sammy-C21 can be ordered with preloaded chip45bootSAM Bootloader. With the free chip45bootSAM Windows GUI the application (hex file) can be uploaded through USB. No additional programming tool is necessary.

You can find further information in the Infosheet.
