Out of stock

The Teensy is a breadboard-friendly development board with loads of features in a, well, teensy package. The Teensy 3.1 brings a 32 bit ARM Cortex microprocessor into the mix so you can do some serious number crunching.

The Teensy 3.1 comes pre-flashed with a bootloader so you can program it using the on-board USB connection: No external programmer needed! You can program for the Teensy in your favorite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for Teensy!

The processor on the Teensy also has access to the USB and can emulate any kind of USB device you need it to be, making it great for USB-MIDI and other HID projects. The 32 bit processor brings a few other features to the table as well, such as multiple channels of Direct Memory Access, several high-resolution ADCs and even an I2S digital audio interface! There are also 4 separate interval timers plus a delay timer! Oh yeah, and all pins have interrupt capability. Also, it can provide system voltage of 3.3V to other devices at up to 100mA.

Frequently Asked Questions

Can Teensy 3.1 be programmed from the Arduino IDE?

Yes. Teensy 3.1 can be programmed with Arduino-style sketches by installing the PJRC Teensyduino support package.

Does Teensy 3.1 require an external programmer?

No. It includes a USB bootloader and can normally be programmed through its onboard USB connection.

Is Teensy 3.1 a current or legacy board?

Teensy 3.1 is a legacy PJRC board. Verify availability, pinout and voltage limits before choosing it for a new design.

Are all Teensy 3.1 pins 5V tolerant?

No. Do not assume every pin or analog input is 5V tolerant. Check the official Teensy 3.1 pinout and electrical limits before connecting a 5V signal.

Can Teensy 3.1 be replaced directly by a newer Teensy board?

Not always. Newer Teensy boards differ in processor, voltage tolerance and peripheral pin mapping, so review hardware and software compatibility before substituting one.
