Teensy LC USB Microcontroller Development Board

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. Teensy-LC

maintains the same form-factor as Teensy 3.1, with most pins offering similar peripheral 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

Teensy-LC has the same powerful USB hardware as Teensy 3.1. 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 CortexM4 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.
