Teensy LC USB Micro-controller Development Board

The Teensy LC USB Micro-controller Development Board 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!

Quick Specifications:

1. 32 bit ARM Cortex-M0+ 48 MHz CPU

3. 13 High-Resolution Analog Inputs
4. 27 Digital I/O Pins (NOT 5V Tolerant)
5. 10 PWM outputs
6. 7 Timers for intervals/delays, separate from PWM
7. 3 UARTs (serial ports)
8. SPI, I2C, I2S
9. I2S (for the high-quality audio interface)
10. 4 Lightweight DMA channels
11. Touch Sensor Inputs

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 provides 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 buffers and even support for RS485 transmitter enable.

Teensy-LC will be ideal for inexpensive “Internet Of Things” projects when paired with an 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 3.2. 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 to 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 3.2.

Analog Input & Output at 12 Bit Resolution:

Analog signals are critically important to many projects. Teensy-LC has 13 pins that 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 3.2. 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!

TODO: expand this section… or add more details about the M0+ vs M4 differences.
