Frequently Asked Questions

Why choose this version without header?
Without pin headers, the Teensy 3.2 can be soldered directly onto a custom board – without the height offset from pin headers. This is ideal for compact enclosures, when specific pin header lengths are needed, or when the Teensy is soldered into an existing circuit. For quick prototyping on a breadboard, the version with soldered headers (K40060h) is more practical.

Is the Teensy 3.2 Arduino-compatible?
Yes. With the free Teensyduino add-on for the Arduino IDE, most Arduino libraries can be used directly. The Teensy runs on a more powerful ARM Cortex-M4 processor with more RAM and significantly higher clock speed than typical Arduino boards.

Can I use the Teensy 3.2 for DMX projects?
Yes. DMX512 can be output directly via the UART interface. The Teensy 3.2 is a popular basis for custom DMX controllers. Matching wireless DMX modules in the shop: Wireless DMX category.

Which displays can I connect?
Via I²C or SPI directly the 0.96" OLED (K40054) or the 1.3" OLED (K40057).
