Info Technical Specs
 

Teensy-LC (Low Cost) is a powerful 32 bit microcontroller board, with a rich set of hardware peripherals. Teensy-LC delivers an impressive collection of capabilities to make modern electronic projects simpler. It features an ARM Cortex-M0+ processor at 48 MHz, 62K Flash, 8K RAM, 12 bit analog input & output, hardware Serial, SPI & I2C, USB, and a total of 27 I/O pins.

Product Contents:
  • Teensy-LC Development Board
  • Pinout Card
Features:
  • Real Hardware Serial
    • Most modern projects involve serial communication with sensors, other chips, other systems, or even the internet. Hardware serial ports greatly simplify projects and enable excellent performance.
    • Teensy-LC provide plenty of serial connectivity: 2 SPI ports, 2 I2C, and 3 Serial ports. All 3 serial ports are supported by high quality drivers in Teensyduino, with both transmit and receive buffering, and even support for RS485 transmitter enable.
    • Teensy-LC will be ideal for inexpensive "Internet Of Things" projects when paired with a ESP8266 Wifi module, which requires a fast hardware serial or SPI port
  • Efficient USB Communication
    • All USB data transfer is done directly to memory with minimal CPU overhead.
    • Teensy-LC supports USB Serial, MIDI, Keyboard (international layouts), Mouse, Joystick, and RawHID protocols. A full set of 16 bidirectional USB endpoints are supported by the hardware, allowing any type of USB device. As more USB protocols are added to Teensyduino, despite its low cost, Teensy-LC will be up the task.
  • Hardware Timers
    • Many Arduino libraries require a hardware timer. Traditional Arduino products have 3 or 4 timers, with only 1 or 2 providing more than 8 bit resolution.
    • Teensy-LC has a total of 7 timers, all of them with 16 or more bits of resolution, to allow excellent compatibility with easy-to-use libraries. Many combinations of popular libraries, which would normally conflict, can seamlessly run together on Teensy LC and Teensy 3.1.
  • Analog Input & Output at 12 Bit Resolution
    • Analog signals are critically important to many projects. Teensy-LC has 13 pins than can function as analog inputs. The effective analog resolution is 12 bits.
    • It also has a true 12 bit digital to analog converter, for an analog output signal.
  • 32 bit ARM Cortex M0+ Processor
    • The Cortex-M0+ processor is a powerful, full 32 bit CPU, designed for lower power, lower cost devices.
    • Cortex-M0+ has fewer instructions and a simpler bus structure than the more powerful Cortex-M4 on Teensy 3.1. For simple code, M0+ often runs at similar speed, when running at the same clock frequency. For math-intensive applications, Cortex-M4 can be significantly faster, and of course it supports higher clock rates.
    • Cortex-M0+ at 48 MHz is much faster than 8 bit AVR processors at 16 MHz, especially when manipulating 16 and 32 bit variables!
  • 5 Volt Buffer For WS2812/NeoPixel LED Projects
    • Teensy-LC provides a 5V output to directly drive WS2812/NeoPixel LEDs.
    • A 74LV1T125 buffer is connected to pin 17, with the increased output voltage available on another pin.

Teensy-LC is a great product. August 22, 2016
By: ovide mercure from boca raton, FL United States  
Easy development board to get started on.  My only grip is the location of analog pins 24 and 25.  The pjrc website is full of useful information on getting started with this product.  One note, which can't be stressed enough: if you are using Linux do not forget to move the 49-teensy.rules file to the rules.d folder.  If you do not do this step the OS will never create the USB device to communicate with the board.  Integration with the Arduino software is smooth, but again in Linux, do not delete the Arduino installation folder before you install the Teensyduino application, it is dependent on a file located there for version information.

Best supplier in over 35 years business October 2, 2015
By: Tim Economu from CLINTON, WA United States  
No question that Erin and Craig are the best in the business at trying to help the customer get what they need. Need something not on the catalog, ask for it. Need something slightly customized. Just ask. Did you know they test all their stuff before you even see it? Does your ebay vendor do that?
I just wish they had their business on Whidbey Island so I could walk over and get the parts and see their smiling faces...
