Engineering inference

Wired networking and industrial control

Ethernet interface for deterministic, wired links.

Engineering inference

Custom USB devices (HID, MIDI, serial)

USB is on the main chip (MIMXRT1062DVJ6B), so the board can enumerate as a keyboard, MIDI device or CDC serial port.

FAQ

Teensy 4.1 questions

What microcontroller does the Teensy 4.1 use?

The Teensy 4.1 is built around the MIMXRT1062DVJ6B, alongside W25Q64JV-DTR (8 MB), DP83825I, GD32E230F8 (after June 2022), TLV75533P (after March 2023; earlier TLV75733P / NCV8186AMN330TAG).

How many GPIO pins does the Teensy 4.1 have?

55 GPIO pins are exposed. Xirkit documents 80 board pins, 55 of them with pin-level electrical limits.

Are the Teensy 4.1 I/O pins 5 V tolerant?

No. The I/O pins are not 5 V tolerant — they run at 3.3 V logic; use a level shifter for 5 V signals. Input-high threshold: 2.31–3.3 V.

How much current can a Teensy 4.1 GPIO pin source?

Documented output-high current per pin: ≤ 4 mA. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.

What voltage powers the Teensy 4.1?

Supply range 3–5.5 V. Power inputs: VIN (3.6–5.5 V), VBAT, VUSB.

How much does the Teensy 4.1 cost?

From $29.95 at www.adafruit.com (2 supplier offers tracked). Prices are observed unit prices before tax and shipping.

What are the Teensy 4.1 dimensions?

60.96 × 17.78 × 1.57 mm. A STEP model is available for enclosure fit checks.

Which interfaces does the Teensy 4.1 support?

gpio, interrupt, adc, pwm, can, i2s, uart, i2c, audio, spi, led, sdio, qspi, control, usb, ethernet.

How do I program the Teensy 4.1?

Supported frameworks: Arduino (Teensyduino), Makefile / command line.

Where does this Teensy 4.1 data come from?

Every value in this record is traced to a source — 3 documents including the board and chip datasheets — with the page and table cited per value. Unknowns are left explicit, never guessed.
