Description
The Teensy 3.6 is the big sibling of the 3.2 — a high-performance microcontroller development board from PJRC, built around the 32-bit ARM Cortex-M4F running at up to 180 MHz. The floating point unit and extra I/O make it a natural fit for demanding audio, MIDI, and DSP projects.
These are genuine new old stock units — factory sealed, never opened. The Teensy 3.6 has been discontinued by PJRC, so sealed stock is increasingly hard to find.
Specs at a glance
- ARM Cortex-M4F @ 180 MHz with hardware floating point
- 1M Flash, 256K RAM, 4K EEPROM
- 58 digital I/O pins, 25 analog inputs
- USB, hardware serial (x6), SPI, I2C, CAN, I2S
- SD card slot (onboard)
- 3.3V logic (most pins 5V tolerant — check datasheet)
- Native USB — appears as MIDI, HID, serial, audio, and more
Ideal for audio and DSP builds, polyphonic synthesizers, complex MIDI controllers, and any project that needs serious processing headroom.
Condition: New old stock — factory sealed, original packaging Compatibility: Works with the Arduino IDE via Teensyduino
