Teensy 3.2 - 32 bit ARM Cortex M4

Development board with microUSB connector (matching cable). MK20DX256VLH7 (ARM) on board, with 72 MHz clock. 34 digital I/O lines in total. 256 kB of Flash, 16 kB RAM, 2 kB EEPROM. Two real ADC (so You can measure two signals in exactly the same moment)

3 UARTs, 1 I2C and SPI port. This board, unlike Teensy 2.0 and Teensy++ 2.0 works with 3.3V logic. Compared to Teensy 3.1 it has power regulator capable to provide 500mA and the board can be powered with 6V voltage. You can program it with Arduino IDE or directly in C/C++ (this second option lets You unleash full ARM potential).

Small footprint (1.4" x 0.7") makes it ideal solution when You need small dev board and powerful processor.

How small are Teensy boards?

Currently, the Teensy family includes 7 boards. Two of them are based on the 8-bit AVR microcontrollers, the remaining 5 boards have a modern 32-bit ARM family chips. Boards dimensions:

• Teensy 2.0 - 30 x 18 mm
• Teensy++ 2.0 - 50 x 18 mm
• Teensy LC - 36 x 18 mm
• Teensy 3.2 - 36 x 1.8 mm
• Teensy 3.5 - 61 x 18 mm
• Teensy 3.6 - 61 x 18 mm
• Teensy 4.0 - 36 x 1.8 mm
• Teensy 4.1 - 61 x 18 mm
