Introducing the Teensy 3.5, the newest member of the Teensy lineup from PJRC! If you're not familiar with Teensy, get ready to be blown away.
Created by Paul Stoffregen from PJRC, the Teensy 3.5 is a microcontroller development board running a 32-bit ARM Cortex M4 processor, which brings a 180MHz clock speed to the table, along with 1MB of flash, 4K of EEPROM, and 62 I/O pins. What makes Teensy special, however, is that along with being programmable directly in C, it also supports programming from the Arduino IDE. That's right, you get the power and flexibility of ARM processors, with the versatility that is Arduino IDE. Here's a quick look at some of the specs that the Teensy 3.5 packs in:
- 120 MHz ARM Cortex-M4 with Floating Point Unit
- 512K Flash, 192K RAM, 4K EEPROM
- Microcontroller Chip MK64FX512VMD12 (PDF link)
- 1 CAN Bus Port
- 16 General Purpose DMA Channels
- 5 Volt Tolerance On All Digital I/O Pins
The Teensy 3.5 breaks out the 62 I/O pins found on the M4 chip, however, only 42 of them are available on the 0.1" headers. The rest can be found as SMD pads underneath the board. The 3.5 is also 5V tolerant which means that you won't damage your board if you connect 5V up to the pins,
Teensy boards have been popular with the maker community for quite some time now due to their native USB support which allows them to behave as HID devices, MIDI devices, and much more. The 3.5 builds on this with a second USB port (on GPIO pins), an Ethernet port, and onboard microSD card support.

- Ethernet mac, capable of full 100 Mbit/sec speed
- Native (4 bit SDIO) micro SD card port
- I2S Audio Port, 4 Channel Digital Audio Input & Output
- 14 Hardware Timers
- Cryptographic Acceleration Unit
- Random Number Generator
- CRC Computation Unit
- 6 Serial Ports (2 with FIFO & Fast Baud Rates)
- 3 SPI Ports (1 with FIFO)
- 3 I2C Ports (Teensy 3.6 has a 4th I2C port)
- Real Time Clock
