    I was wondering if it is straightforward to control the tinyg with an arduino rather than with a computer connected through USB (perhaps using the arduino as an sdcard reader, for example)?

    Would it require any hardware or firmware mods?

    I sort of thought you might be able to use the same pins the USB connector is hooked up to, but was having trouble telling from the hardware page whether these had headers attached to them. (I’m a bit of a newb)

    Thanks,

    It should be possible to drive TinyG from the Arduino RX and TX lines. There is a 3 pin female header right above the reset button that is labeled for Arduino connection. Follow the instructions on the board silkscreen and connect the RX to the Arduino TX line, the TX to the Arduino RX line, and the ground to the Arduino ground. You will also need to put a jumper on J17, which is the 2 pin male connector located to the left of the Arduino connector (in between the shrouded programming header and the FTDI USB chip). Remember that the board is running at 115,200 baud, so will need to set your serial lines to that baud rate.
