@lige Beautiful 
Your next boards will have the castellated edges right?
And its cheap and easy for us to make boards in the USA so for a lot of us just having the Eagle or other PCB files to have boards ran or modified slightly would be great. Are you OK with sharing your design files?
Has anyone put out an eagle board/schematic yet? I’d buy a board like the one above but have some customization to do and would rather start with a known good base design.
Also partly related, I’ve been reading that leaving USB/JTAG open is poor security, test boards would have them but is there a way to secure usb unless the board is running a special firmware? Suggestions on how to secure those interfaces from tampering is welcome! I know a determined and skilled person can always get in as physical access is total access but I also don’t want the device to be open to malicious tampering because I left jtag headers on that don’t seem to be required for user interaction.
@LukeUSMC Here is a alternative to the standard JTAG connector: P1 - Custom Board Design Questions
And the Sparkfun P1 Red board has the eagle schematic and files available which makes a good starting point, that is what I used.
Hi! Awesome PCB that you made!
Will you share the design files?
Thanks a lot!
