Teensy LC – Coming March 2015
Teensy-LC (Low Cost) is a powerful 32 bit microcontroller board, with a rich set of hardware peripherals, at a very affordable price!
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. See the technical specifications and pinouts below for details.
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.
