This Teensy-Board is the successor of the well-known Teensy series.
The new Teensy 4.0 is 5x faster than its predecessor, Teensy 3.6, and thus copes with the tasks assigned to it much faster.
The Teensy 4.0 is a complete USB-based microcontroller development system with very small dimensions.
All programming is done via the USB interface.
No special programming device is required, just a standard mini-B USB cable and a PC or Macintosh with a USB interface.
