SPIDER Automation Teensy 3.5 Development Board | 120MHz ARM Cortex-M4
Description
SPIDER Automation Teensy 3.5 Development Board is a complete, USB-based high-performance microcontroller system designed for demanding embedded projects. Powered by an MK64FX512VMD12 32-bit ARM Cortex-M4 processor running at 120 MHz with a hardware floating-point unit, the Teensy 3.5 packs incredible computing muscle, ample memory, and extensive peripheral support into a compact breadboard-friendly footprint.
Pre-flashed with a bootloader, the Teensy 3.5 allows instant programming via its onboard USB connection without requiring an external hardware programmer. You can write code using C in your favorite editor or leverage the Teensyduino add-on for the Arduino IDE. With native USB device emulation, multiple DMA channels, 25 analog inputs, dual DACs, an Ethernet MAC, a CAN bus port, and a native 4-bit micro SD card socket, it provides an unmatched platform for advanced audio, sensor, and robotics projects.
