NEW PRODUCT – Teensy 3.0 + header

Window-347

NEW PRODUCT – Teensy 3.0 + header. Teensy 3.0 is a small, breadboard-friendly development board designed by Paul Stoffregen and PJRC. Teensy 3.0 will bring a low-cost 32 bit ARM Cortex-M4 platform to hobbyists, students and engineers, using an adapted version of the Arduino IDE (Teensyduino) or programming directly in C language.

Window-1-206

Based on a 32 bit ARM chip, Teensy 3.0 aims to greatly increase the computing capability and peripheral features, but maintain the same easy-to-use platform that has made Teensy 2.0 so successful.

Please note: Teensy 3.0 and 2.0 are not official Arduino-brand products. Although the Teensyduino IDE has been adapted so that many simple Arduino projects will work with the Teensy, there will still be a lot of libraries and shields that will not work with this device! If you’re new to microcontrollers, we suggest going with a classic Arduino UNO since all Arduino projects, examples and libraries will work with it.

Technical Specifications:

  • 32 bit ARM Cortex-M4 48 MHz CPU (M4 = DSP extensions) Here is Freescale’s datasheet for the chip (warning 1227 pages)
  • 128K Flash Memory, 16K RAM, 2K EEPROM
  • 14* High Resolution Analog Inputs (13 bits usable, 16 bit hardware)
  • 34* Digital I/O Pins (10 shared with analog)
  • 10 PWM outputs
  • 8 Timers for intervals/delays, separate from PWM
  • USB with dedicated DMA memory transfers
  • 3 UARTs (serial ports)
  • SPI, I2C, I2S, IR modulator
  • I2S (for high quality audio interface)
  • Real Time Clock (with user-added 32.768 crystal and battery)
  • 4 general purpose DMA channels (separate from USB)
  • Touch Sensor Inputs

This board is super new, so most of the information, documentation and specs are only up on the Kickstarter page. Please check it out for more details!

  1. Is it possible to get one without the bootloader and just program it like a regular ARM chip?

  2. I don’t think so, the bootloader however is in a separate chip on this board. You do not loose flash space or bootup time to the bootloader but have the advantage of an easy, push-button loader which will accept a hex file from your choice of toolchains.

  3. If you really want an Arduino-free board for Freescale ARM MCUs, have a look at the FRDM-KL25Z. Silicon vendors are really getting the cheap dev board religion these days.

  4. …I’ll add there’s the recent galago? kickstarter and a few other ARM dev boards trying to do something similar…all of them seem to promise a lot on the software and then only show their hardware – for me, and I assume most others, the software is the most important component, ARM chips and cheap dev boards are everywhere now, easy toolchain setup with example code, not so much

    I’ll bite on one of the competitor dev boards when there are actual examples of them being used by their creators, show me real examples with microSD DMA data logging of A/D’s while streaming over ethernet and a couple of PWM outs, etc. and how you set it up – I don’t care that you can toggle an led…

    Maple was exciting… and then fizzled

    mbed is as good as it gets at the moment but comes w/ lots of restrictions and a fairly steep price

    I’m sure a critical mass will eventually build around one of these dev boards, but until then I think the best route for ARM is a discovery + rtos, the PX4 project has the best docs + bootloader +nuttx that I’ve seen so far

  5. I’ve bought one and only now did I think to check the pjrc website for support – it looks like the latest version of Teensyduino doesn’t make mention of this board. Does anyone know what IDE support exists? The kickstarter page talks of the future which has arrived.
