Teensy ® USB Development Board The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port.

Teensy 4.1 has a voltage regulator which reduces the 5V VUSB / VIN power to 3.3V for use by the main processor and most other parts. Additional circuitry may be powered from the 3.3V pin. The recommended maximum for external 3.3V usage is 250mA. Teensy 4.1 is not meant to receive power on its 3.3V pin, but this can be done with special modificaton.

Teensy 4.0 has a voltage regulator which reduces the 5V VUSB / VIN power to 3.3V for use by the main processor and most other parts. Additional circuitry may be powered from the 3.3V pin. The recommended maximum for external 3.3V usage is 250mA. Teensy 4.0 is not meant to receive power on its 3.3V pin, but this can be done with special modificaton.

Teensy-LC has RTC logic on-chip, but lacks the 32.786 kHz crystal oscillator & VBAT battery backup power pin. An internal oscillator can be used but the accuracy is poor. This table shows zero, to give you an honest summary of the hardware's real capability.

The first step is to plug your new Teensy in using the USB cable. Simply plug the Teensy board in to a USB port to get started. All brand new Teensy boards come with the LED blink program pre-loaded.

Teensyduino is a software add-on for the Arduino, to run sketches on the Teensy and Teensy++! Running Sketches on the Teensy Most programs written for Arduino work on Teensy. All of the standard Arduino functions (digitalWrite, pinMode, analogRead, etc) all work on Teensy. Teensyduino is also compatible with many Arduino libraries.

Teensy Loader now recognizes ARM elf format, will not accidentally program Teensy 3.0 code to a pre-3.0 board. Teensy Loader version number is now in sync with Teensyduino version. Fix stall when connected to a Raspberry Pi that reboots

To use Teensy you will need the Arduino IDE software. Materials Required. Teensy 4.0 with Pins; Solderless Breadboard; USB Cable Computer with USB First Hardware Check Before installing software, you can simple plug Teensy 4.0 in to check if it is working. First plug Teensy into the solderless breadboard, so it has a sturdy base, then connect ...
