armcan solderpad
A PCB with an AT91SAM7X128 processor with galvanically isolated CAN bus and power running off 24V DC.
oao.no/wpe/2009/12/arm-with-can-interface/Description
This board was designed for the purpose of processing messages transmitted over a CAN bus.
A PLC with moderate capabilities transmit a few variable values over the CAN-bus, this card process the values and transmits the result, which the PLC uses in it's own program execution. The response time for a PID-controller is less than 1 usec.
Features:
- CPU with 256 KB Flash
- Isolated 18-36 V DC supply
- Isolated power and CAN bus
- 2 USB ports, one for programming and one for serial port 0
- 1 TTL level serial debug port
- Serial number chip
- JTAG connector for debugging and programming
- 2 serial IIC EEPROMs
- Micro controller drives erase/reset signals for programming
