    Does the Linux-side offer any services to easily access Key/Value-DB's or processes like the Arduino-Yun Bridge does?
  2. Identifying the different teensy models

    Hi

    Under https://www.pjrc.com/teensy/troubleshoot.htmlit is noted that every teensy has a special VID/PID. Is there a list somewhere for reference?

    Thank you, Dani
