Description
The module has small size and great potential. It is equipped with a 32 bit microcontroller with the core ARM Cortex M4 72 MHz, 256 KB of Flash, 64 KB of RAM. It has 34 pins of I/o, 12 of which are PWM channels and 21 are analog inputs, the DMA controller and popular communication interfaces: SPI, I2C, I2S, CAN. Leads operates with a voltage of 3.3 V, however, they tolerate a value of 5 V.
Teensy has an efficient 3.3 V regulator that can power directly other modules, such as the popular wi-fiESP8266. Unlike theArduino Micro, it does not have connectors and reset button. The user decides which leads will be needed so the board can maintain their small size. The kit does not contain golpin connectors, they can be purchased seperately and self-soldered.
Inputs/outputs
The system has 34 pins of I/O. They all have the capability of interrupting the handling. Between them are 21 analog inputs of high-resolution, 12 PWM outputs, 7 timers, 3 UART interfaces, SPI interface, I2C, I2S, CAN Bus, RTC module, 16 channels DMA and outputs of touch sensor.
The distribution of the leads of Teensy 3.2, a detailed description can be found onthe website of the manufacturer.
Programming
The module has uploaded bootloader so that it can be programmed using the built-in micro usb connector, without the need of an external programmer. For this purpose, you can use any environment of C language or, after uploading the extensionteensyduino, through the Arduino IDE.
