The Teensy is a breadboard-friendly development board with loads of features in a, well, teensy package. The Teensy LC (Low Cost) is a 32 bit microcontroller board that provides you with an uncomplicated option for getting started with the Teensy line of products without breaking the bank!

The Teensy LC comes pre-flashed with a bootloader so you can program it using the on-board USB connection: No external programmer needed! You can program for the Teensy in your favorite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for Teensy!

The processor on the Teensy also has access to the USB and can emulate any kind of USB device you need it to be, making it great for USB-MIDI and other HID projects. The 32 bit processor brings a few other features to the table as well, such as multiple channels of Direct Memory Access and an I2S digital audio interface! There are also 2 separate interval timers! Also, the Teensy LC can provide system voltage of 3.3V or 5V to other devices at up to 5-20mA.

All of this functionality is jammed into a 1.4 x 0.7 inch board with all headers on a 0.1" grid so you can slap it on a breadboard and get to work! So, what sets the Teensy LC apart from the Teensy 3.1? First off, this version has been streamlined to be as cost effective as possible. Obviously, the LC doesn’t share a lot of power that the 3.1 possesses but by no means does it make the LC a ‘weak’ board! The Teensy LC is equipped with 8kB RAM, 62kB of flash memory, and 27 Digital I/O pins with 13 high res Analog inputs.

Note: The Teensy LC does not come with a micro-B USB cable, please check the Recommended Products section below for an appropriate one.

Features:

32 bit ARM Cortex-M0+ 48 MHz CPU
62kB Flash Memory, 8kB RAM, 1/8(emu)kB EEPROM

10 PWM outputs
7 Timers for intervals/delays, separate from PWM
3 UARTs (serial ports)
SPI, I2C, & I2S
I2S (for high quality audio interface)
4 Lightweight DMA channels
Touch Sensor Inputs
1.4 x 0.7" (~35 x 18 mm)

該Teensy是麵包板友好的開發板的，好了，teensy包的功能負荷。該Teensy LC（低成本）是一個32位微控制器板，為您提供了入門產品線Teensy沒有打破銀行一個簡單的選擇！

該Teensy LC自帶閃現前有引導程序，因此您可以使用主板上的USB連接它進行編程：無需外部程序員需要！您可以使用C在你最喜歡的節目編輯程序的Teensy 或者可以安裝Teensyduino附加的Arduino的IDE，寫Arduino的草圖Teensy！

在Teensy該處理器還可以訪問USB和可以模擬任何類型的USB設備，你需要它，使得它非常適合USB-MIDI等HID項目。 32位處理器帶來了其他一些功能表中為好，如直接內存訪問多個通道和I2S數字音頻接口！也有2個獨立的間隔計時器！另外，Teensy LC能夠以高達5-20mA提供3.3V或5V的系統電壓至其它設備。

所有這些功能都塞進一個1.4×0.7英寸板在0.1“網格中的所有標題，所以你可以拍它放在一個麵包板開始工作！那麼，究竟從Teensy 3.1與眾不同的Teensy LC？首先，這個版本已經精簡，以作為成本效益越好。顯然，LC不共享大量的電力的3.1，但具有絕非它使LC一個“弱”板！在Teensy LC配備8KB的RAM，閃存的62KB，並與13高分辨率模擬輸入27數字I / O引腳。

注意：Teensy LC沒有附帶微型B USB電纜，請檢查下面的推薦產品部分恰當的。
