ATmega64M1-Development-Board (Arduino-Compatible)

This projects brings an Arduino-compatible development board for the Atmel ATmega64M1 microcontroller. The ATmega64M1 is an 8-bit AVR RISC-based microcontroller and with the CAN capabilities widely used in the automotive industry.

The microcontroller has some additional features to the widely-used Arduino UNO:

CAN interface
DAC
internal temperature sensor

With the help of ATmegaxxM1-C1 Arduino Core of thomasonw (https://github.com/thomasonw/ATmegaxxM1-C1) it is possible to work with the Arduino environment on this board. But you are also able to program the board directly via an ICSP and a dedicated programmer.

Notes

CAN Interface

The CAN interface can be handled by two CAN transceivers. You can choose between an isolated (ADM3053) and a non-isolated (MCP2562) CAN transceiver. If you are using the ADM3053, you have to equip the board with R6 and C12 to C15. C5 to C8 are mandatory for both configurations.

Power Supply

You power the board via three different ways: USB, VIN (DC-Jack or pin header) or CAN interface (3: GND and 9: VCC). You can configure the power supply via the jumper JP2 and JP3 next to the DC-Jack. If you are using the CAN interface as power provision, you have to close the solder jumper SJ4 next to the CAN interface. Caution: If you are closing this jumper the grounds of the board and CAN interface are no more isolated to each other!
