eensy 3.2 & 3.1 - New Features
Teensy 3.2
Teensy 3.2 has dedicated 3.3V regulator.穩壓
Teensy 3.1
Teensy 3.1 has gold plating for easier soldering.更新接點
Teensy 3.0
Teensy 3.0 has standard tin plating finish.標準版
Teensy 3.2 and 3.1 have the same size, shape & pinout; and are compatible with code written for Teensy 3.0. All are well supported on the Arduino IDE using Teensyduino.
Teensy 3.1 adds several new features, due to an upgraded microcontroller. Here are the highlights. A table of technical specifications is show below.
Teensy 3.2 adds a more powerful 3.3 volt regulator, with the ability to directly power ESP8266 Wifi, WIZ820io Ethernet and other power-hungry 3.3V add-on boards.加入穩壓電源與wifi網路
More Memory For Awesome Projects
The RAM has quadrupled since 3.0, from 16K to 64K. 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 & 3.1.
Flash memory has also doubled, to 256K, and provides double the memory bandwidth.
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 digital inputs.
All digital pins are 5 volt tolerant on Teensy 3.2 & 3.1. However, the analog-only pins (A10-A14), AREF, Program and Reset are 3.3V only.
Update: Color Change Jan 22, 2014
The color of Teensy 3.1 was changed from black to green on January 22, 2014.
