Its classed as a "compatible Teensy Tiny"
Firstly, If I'm in the wrong place I apologise and if I'm asking the wrong questions I again apologise, my knowledge of these things is ZERO, its a project I spotted which would be useful and I can solder but using these boards is new to me.
Here's the board
I need to write a hex file / firmware to the board
I got avrdude and entered a supplied commandline under Win 7 X64
avrdude -c avr109 -p m32u4 -P /dev/tty.usbmodem411 -v -U flash:w:swc_usb.hex:i
Avrdude spat out an error re the usbmodem....
I got no drivers with the item and upon reading a help file it said if its been ran from usb then use -P usb but that spat out errors.
Could someone please help the village idiot do this. When I connected the board with the mini USB lead it claimed to recognise it, something about a USB input device. That was after I pressed the button to stop it flashing as I'd read that activated a bootloader which I thought meant it could be recognised.
Now the guy uses a python script to send files to this when its flashed and I'm again a newb to python but researching the avrdude error it said something about Pyserial and click which somehow I managed to install with Pip but beyond that I'm lost. I looked in the device manager and there's no com ports at all.
Once done I'll never come back, that's a promise
