Datasheet

as its sibling, the Teensy 3.6) is larger, faster and capable of more projects, especially
with its on board micro SD card port. An upgraded ARM Cortex MCU (120MHz from
72MHz), more memory (512K from 256K), as well as more RAM, EEPROM and
accessible pins make up the key new features of this "teensy" board. The Teensy 3.5 is
slightly scaled down from the Teensy 3.6 but is offered at a cheaper price point,
comparatively.
Note: This does not come with a USB cable
