- 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 buffering, and even support for RS485 transmitter enable. Teensy-LC will be ideal for inexpensive IOT projects when paired with a ESP8266 Wifi module, which requires a fast hardware serial or SPI port.
- 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 the task.
- Specs: ARM Cortex-M0+ processor at 48 MHz, 62K Flash, 8K RAM, 12 bit analog input and output, hardware Serial, SPI and I2C, USB, and a total of 27 I/O pins
