Teensy 3.2 has a second ADC, so you can concurrently measure 2 analog signals. With analogRead(), you can measure many signals, but only 1 at a time. Simply use analogWrite() on the A14 pin for true analog output. The output is created by the stable reference voltage, so it's doesn't vary if your power supply voltage changes slightly. You can always filter PWM, but true analog output responds rapidly. However, the analog-only pins (A10-A14), AREF, Program and Reset are 3.3V only. These can now be directly connected to Teensy 3.2's digital inputs.Īll digital pins are 5 volt tolerant on Teensy 3.2. Today most new chips use 3.3V signals, but many legacy products output 5 volt digital signals. Icons and graphics for color displays and audio effects requiring delays, like reverb and chorus, will become possible on Teensy 3.2. While 16K is plenty for nearly all Arduino libraries, 64K allows for more advanced applications.

The product is supplied without headers, so if you need some, please have a look at the 'Related Products' tab above. Also, it can provide system voltage of 3.3V to other devices at up to 100mA.Īll of this functionality is jammed into a 1.4 x 0.7 inch board with all headers on a 0.1" grid so you can slap in on a breadboard and get to work! 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. 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. Teensy 3.2 has the same size, shape & pinout is compatible with code written for Teensy 3.0/3.1, and is well supported on the Arduino IDE using Teensyduino. No external programmer needed! You can program for the Teensy in your favourite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for Teensy! The Teensy 3.2 comes pre-flashed with a bootloader so you can program it using the on-board USB micro-B connector. The Teensy 3.2 brings a 32 bit ARM Cortex microprocessor into the mix so you can do some serious number crunching. The Teensy breadboard-friendly development board with loads of features in a, well, teensy package. These higher limits are intended to allow Teensy 3.2 to be more rugged when used with non-USB power sources which aren't well regulated 5 volt sources. However, the actual regulator chip is capable of up to 10 volts input, and up to 500 mA output. The Teensy 3.2's power output is specified at 250 mA and the maximum voltage input at 6 volts, due to PCB thermal dissipation limits. The main change is an improved 3.3V regulator, to allow Teensy to directly power ESP8266 Wifi, WIZ820io (W5200) Ethernet, and other power-hungry 3.3V devices. It is fully compatible with all shields and add-on boards made for Teensy 3.1
Teensy 3.2 is a direct, 100% compatible replacement for Teensy 3.1. Estimated availability of additional stock not before early 2023. Availability Note: Product currently out of stock with the manufacturer due to the global chip shortage.
