Description
The Teensy 3.2 is a compact, powerful microcontroller development board from PJRC, based on the 32-bit ARM Cortex-M4 running at up to 72 MHz. It punches well above its size for audio, MIDI, and USB projects, and has a huge community and library ecosystem behind it.
These are genuine new old stock units — factory sealed, never opened. The Teensy 3.2 has been discontinued by PJRC, so sealed stock is increasingly hard to find.
