    Setup Arduino IDE and bootloader

    I am using Atmel-ICE, I have no idea about another way how to program bootloader now!

    Arduino > Preferences : Additional boards manager URLs ADD https://www.mattairtech.com/software/arduino/beta/package_MattairTech_index.json

    Arduino > Tools > Boards manager : MattairTech MT-D21E (rev B) 

    Arduino > Tools > Clock > Source : INTERNAL_OSCILLATOR 

    Arduino >Tools > Serial config : ONE_UART_ONE_WIRE_TWO_SPI

    Connect GND, VCC, SWC, SWD, Reset to ATMEL-ICE

    Arduino > Tools > Programmer : ATMEL-ICE Arduino > Tools > BURN BOOTLOADER

    • Now you can upload sketches with USB

    Or second option:

    From Atmel Studio write special ARMABOT.bin then you can easy upload firmwares drag&drop

Do you have the PCB/Schematic for the new 49-key keyboard? If so, could you please post them -- would greatly appreciate it :)

  Are you sure? yes | no

Has anyone designed a case for this little beauty?

  Are you sure? yes | no

I have the earlier version of this keyboard (with just the two SHIFT/FN LEDs) and would like to modify the firmware. Where can I find the source code of the preinstalled firmware?

  Are you sure? yes | no

Oh I didn't think that was the same as the board design looks very different ^^. I'll try it out with that code, thanks

Any idea when the next version will be available for sale? I really like the new layout on that one (the current one has a few problems if you want to control a terminal-based system...)

  Are you sure? yes | no

but the images don't match the files, why?

  Are you sure? yes | no

looking forward to the details of this one. I like the PTH for the buttons instead of NPTH on the 4 row one. it looks great with black and ENIG!

  Are you sure? yes | no
