SPIDER Automation Teensy 3.2 Development Board | 72MHz ARM Cortex-M4
Description
SPIDER Automation Teensy 3.2 Development Board is a direct, fully compatible evolution of the popular Teensy 3.1 architecture, engineered for serious number crunching and advanced embedded development. Measuring just 1.4 x 0.7 inches, this breadboard-friendly module packs an extraordinary array of high-end features into a tiny footprint, making it a favorite among engineers, audio designers, and makers.
Powered by a 32-bit ARM Cortex-M4 CPU running at 72 MHz with DSP extensions, the Teensy 3.2 includes an upgraded 3.3V regulator capable of delivering up to 250mA—allowing it to directly power external, power-hungry devices like ESP8266 Wi-Fi modules and WIZnet Ethernet boards. Pre-flashed with a USB bootloader, it enables instant code uploading via its micro-USB connector without requiring an external programmer, supporting both standard C editing and seamless integration into the Arduino IDE via Teensyduino.
Key Features
- 72 MHz ARM Cortex-M4 CPU: 32-bit processor core incorporating specialized DSP extensions for efficient mathematical calculations.
- Expanded Memory Capacity: 256 KB of Flash program memory, 64 KB of RAM for graphics or audio buffering, and 2 KB of EEPROM.
- Upgraded 3.3V Power Regulator: Provides up to 250mA regulated output current to reliably power peripheral communication modules.
- 5V-Tolerant Digital Pins: All standard digital I/O pins accept 5V logic signals directly, simplifying multi-voltage breadboard wiring.
- High-Resolution Analog Peripherals: 21 analog inputs (13 bits usable, 16-bit hardware resolution) paired with a true 12-bit DAC analog output.
- Extensive Communication Interfaces: CAN Bus, I2S digital audio interface, 3 UART serial ports, SPI, and 2 I2C interfaces.
- Hardware Timers & DMA: 7 independent interval/delay timers separate from PWM, plus 16 general-purpose Direct Memory Access channels.
- Native USB Device Emulation: Full-speed USB port capable of emulating USB-MIDI, keyboards, mice, joysticks, and custom HID devices.
Benefits
- Ample Overhead for Complex Tasks: 64KB RAM easily accommodates audio effects like reverb/chorus, complex sensor fusion algorithms, and color display graphics.
