DETAILED DESCRIPTION
A Teensy Clone?
Based on the Teensy 3.2 schematic.
While this is essentially a clone of the actual Teensy 3.2, know that it is NOT identical in PCB layout, because the original Teensy is not an open source hardware design. Paul Stoffregen has created an awesome product in the Teensy series, and managed to make the costs very low considering the power of the Kinetis device on it, and all the hard work going into his libraries and software tools is worth supporting. So I highly recommend using the original Teensy 3.2 as your prototyping tool and when you're ready to create a custom PCB based on it, use this project here as your starting point, and fork it. Remember when forking to change the name of your new project as CircuitMaker currently only gives you one shot for setting the right project name.
About this board
Here are a few important facts about this design and the circuit itself:
- Central device: Freescale (now NXP) Kinetis K20 ARM-Cortex M4 (MK20DX256VLH7)
- 256KB Program Flash
- 64KB SRAM
- 72MHz Clock (Overclockable to 96MHz)
- 3.3V supply
- "Breadboard Friendly" - all IOs are on 0.1" pitch grid
- Pin Compatible with Paul's Teensy 3.1 and 3.2
A project goal (which may be difficult or impossible due to size constraints) is to expose the SWD pins for debug using Kinetis Design Studio.
