Best pjrc teensy 3.2 reviews

1. Teensy++ 2.0

Feature

8-Bit AVR Processor (AT90USB1286)
128K Flash Memory, 8K RAM, 4K EEPROM
USB Can Emulate Any Type of Device
Single Pushbutton Programming
Arduino Compatible

2. Audio Adaptor Board for Teensy 3.0 3.6

Feature

This audio adapter lets you easily add high quality 16 bit, 44.1 kHz sample rate (CD quality) audio to your projects with a Teensy 3.2 , 3.5 or 3.6 .
The audio chip connects to Teensy v3 using 7 signals. The I2C pins SDA and SCL are used to control the chip and adjust parameters. Audio data uses I2S signals, TX (to headphones and/or line out) and RX (from line in or mic), and 3 clocks, LRCLK (44.1 kHz), BCLK (1.41 MHz) and MCLK (11.29 MHz). All 3 clocks are created by the Teensy. The SGTL5000 chip operates in "slave mode", where all its clock pins are inputs.

3. PJRC Teensy 3.2

Feature

32 bit ARM Cortex-M4 72 MHz CPU (M4 = DSP extensions) 256K Flash Memory, 64K RAM, 2K EEPROM
21 High Resolution Analog Inputs (13 bits usable, 16 bit hardware) 34 Digital I/O Pins (5V tolerance on Digital Inputs) 12 PWM outputs
7 Timers for intervals/delays, separate from PWM USB with dedicated DMA memory transfers
3 UARTs (serial ports) SPI, I2C, I2S,CAN Bus, IR modulator I2S (for high quality audio interface)
The Teensy 3.2 adds a more powerful 3.3 volt regulator, with the ability to directly power an ESP8266 Wifi, WIZ820io Ethernet, and other 3.3V add-on boards that require a little more power

4. Teensy 3.2 (with Pins)

Feature

Teensy 3.2 and 3.1 have exactly the same pinout.
Teensy 3.2 provides more power on its 3.3V pin, and accepts a wider voltage input range.

5. Teensy LC USB Development Board Without Pins

Feature

32 bit ARM Cortex-M0+ 48 MHz CPU 62kB Flash Memory, 8kB RAM, 1/8(emu)kB EEPROM
13 High Resolution Analog Inputs 27 Digital I/O Pins (NOT 5V Tolerant)
10 PWM outputs 7 Timers for intervals/delays, separate from PWM
3 UARTs (serial ports) SPI, I2C, & I2S I2S (for high quality audio interface)
4 Lightweight DMA channels Touch Sensor Inputs

6. Teensy 3.6 (Without Pins)

Feature

180 MHz ARM Cortex-M4 with Floating Point Unit
1M Flash, 256K RAM, 4K EEPROM
Microcontroller Chip MK66FX1M0VMD18

7. Teensy 3.6 with pins

Feature

180 MHz ARM Cortex-M4 with Floating Point Unit
1M Flash, 256K RAM, 4K EEPROM
Microcontroller Chip MK66FX1M0VMD18
Pre-soldered header pins

8. Teensy 3.5 with pins

Feature

120MHz ARM Cortex-M4 with Floating Point Unit 512K Flash, 192K RAM, 4K EEPROM
1 CAN Bus Port 16 General Purpose DMA Channels 5V Tolerance on All Digital I/O Pins 62 I/O Pins (42 breadboard friendly) 25 Analog Inputs to 2 ADCs with 13-bit resolution 2 Analog Outputs (DACs) with 12-bit resolution 20 PWM Outputs (Teensy 3.6 has 22 PWM)
6 Serial Ports (2 with FIFO and Fast Baud Rates) 3 SPI Ports (1 with FIFO) 3 I2C Ports Real-Time Clock
Teensy 3.5 with Microcontroller Chip MK64FX512VMD12

9. PJRC Teensy 4.0 (Without pins)

Feature

1024K RAM (512K is tightly coupled)
2048K Flash (64K reserved for recovery & EEPROM emulation)
2 USB ports, both 480 MBit/sec
3 CAN Bus (1 with CAN FD)
