Description
Reviews

The Teensy 3.2 Development Board serves as a direct and fully compatible replacement for the Teensy 3.1, seamlessly working with all shields and add-on boards designed for its predecessor. Notably, it features an enhanced 3.3V regulator, enabling direct power supply to power-hungry 3.3V devices like ESP8266 Wifi and WIZ820io (W5200) Ethernet.

With a specified power output of 250 mA and a maximum voltage input of 6 volts, the Teensy 3.2’s regulator chip can handle up to 10 volts input and output up to 500 mA, providing ruggedness when used with non-USB power sources. This makes it suitable for a variety of applications.

Despite its compact size, the Teensy 3.2 boasts a 32-bit ARM Cortex microprocessor, allowing for powerful number crunching. It comes pre-flashed with a bootloader, eliminating the need for an external programmer, and can be programmed using the onboard USB micro-B connector. Compatibility with Arduino IDE is achieved through the Teensyduino add-on, facilitating the development of Arduino sketches for Teensy.

Teensy 3.2 maintains the same size, shape, and pinout as its predecessor (Teensy 3.0/3.1) and supports code written for these versions. The 32-bit processor introduces additional features such as multiple channels of Direct Memory Access (DMA), high-resolution ADCs, an I2S digital audio interface, interval timers, and interrupt capability for all pins. It can even provide a system voltage of 3.3V to other devices at up to 100mA.

All these features are packed into a 1.4 x 0.7-inch board with headers on a 0.1″ grid, making it breadboard-friendly for easy integration into projects.

Here are the highlights for Teensy 3.2

Large Memory For Awesome Projects

64K RAM. While 16K is plenty for nearly all Arduino libraries, 64K allows for more advanced applications. Icons and graphics for color displays and audio effects requiring delays, like reverb and chorus, will become possible on Teensy 3.2.

256K Flash program memory.

5 Volt Tolerance on Digital Inputs

Today most new chips use 3.3V signals, but many legacy products output 5 volt digital signals. These can now be directly connected to Teensy 3.2’s digital inputs.

All digital pins are 5 volts tolerant on Teensy 3.2. However, the analog-only pins (A10-A14), AREF, Program, and Reset are 3.3V only.

12 Bit Analog Output

Teensy 3.2 has a proper analog output. You can always filter PWM, but true analog output responds rapidly. The output is created by the stable reference voltage, so it’s doesn’t vary if your power supply voltage changes slightly.

Pinouts

Teensy 3.2 is meant to be a drop-in replacement for Teensy 3.0/3.1. Only 1 pin has different functionality from Teensy 3.0. The reset pin was replaced by A14/DAC, which you can use for true analog output, or as another analog input.
