Teensy 3.2 is an upgrade to the Teensy 3.1. 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.

Teensy 3.2's power output is rated at 250mA with a max voltage input at 6 volts, due to PCB thermal dissipation limits. However, the actual regulator chip is capable of up to 10V DC input, and up to 500mA output. 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.

Teensy 3.2 is fully compatible with all shields and add-on boards designed for Teensy 3.1. It preserves the same size, pinout, and processor as Teensy 3.1.

The bootloader chip has also been changed from Mini54 to KL02 (the same as Teensy LC).
