PJRC TEENSY 4
#############
Overview
********
The Teensy is a complete USB-based microcontroller development system, in a
very small footprint, capable of implementing many types of projects. All
programming is done via the USB port.

Programming and Debugging
*************************
Flashing
========
Build applications as usual (see :ref:`build_an_application` for more details).
Flash hex-file with the documented tools:
.. _Teensy flash tools:
https://www.pjrc.com/teensy/loader.html
Debugging
=========
Console output is mapped to teensy pins 0 (RX1) and 1 (TX1). Connect a usb-to-serial adapter
to use this serial console. Use the following settings with your serial terminal of choice (minicom, putty,
etc.):
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
