Paul Stoffregen has been making Teensy USB MCU development boards since 2008, and has just launched the latest Teensy 3.5 & 3.6 boards powered by NXP (previously Freescale) Kinetis K64 & K66 ARM Cortex-M4 MCUs with a micro USB port for power and programming, a micro SD slot, and several I/Os.
- Teensy 3.5 (T3.5) – NXP Kinetis K64 ARM Cortex M4 MCU @ 120 MHz with FPU, 512KB flash, 192 KB RAM, 4K EEPROM
- Teensy 3.6 (T3.6) – NXP Kinetis K66 ARM Cortex M4 MCU @ 180 MHz with FPU, 1MB flash, 256KB RAM, 4K EEPROM
- Storage – micro SD card port
- USB – 1x USB Full Speed (12 Mbit/sec) Port; T3.6 only: 480 Mbit/sec host port
- Connectivity – 10/100M Ethernet mac
- 62x I/O Pins (42 breadboard friendly)
- 25x Analog Inputs to 2 ADCs with 13 bits resolution
- 2x Analog Outputs (DACs) with 12 bit resolution
- 20x PWM Outputs
- 6x Serial Ports (2 with FIFO & Fast Baud Rates)
- I2S Audio Port, 4 Channel Digital Audio Input & Output
- 3x SPI Ports (1 with FIFO), 4x I2C Ports
- CAN bus – T3.5: 1x; T3.6: 2x
- 14x Hardware Timers
- General Purpose DMA channels – T3.5: 16x; T3.6: 32x
- 11x Touch sensing inputs (T3.6 only)
- Security – Cryptographic Acceleration Unit, Random Number Generator, CRC Computation Unit
- Misc – Real Time Clock; Teensy 3.5 only: 5V tolerance on all digital I/Os.
- Dimensions – N/A
The boards launched on Kickstarter yesterday, and already vastly surpassed its funding target having raised around $45,000 from 700+ backers out of a goal of $5,000. Teensy 3.5 requires a $23 pledge, while you’ll need to pledge $28 for Teensy 3.6. Shipping adds $4 to $5 to the costs, and delivery is scheduled for October 2016.
