The Silicon Railway LEDuino product has gone to revision B with even more added features.
- Support for self-programming of boot-loader using the avrdude-serjtag option with the FT232R - modify your boot loader and burn it without a programmer.
- Auto-reset disable option, to disable the Arduino auto-reset feature, no mods, just shift a jumper.
- Enhanced CAN bus controller circuitry to be more compatible with a wider range of software, including better support for interrupts.
