Teensy 4.0 questions
What microcontroller does the Teensy 4.0 use?
The Teensy 4.0 is built around the MIMXRT1062DVL6B, alongside W25Q16JV-DTR (2 MB), GD32E230F8 (after June 2022), AP7366 (after March 2022).
How many GPIO pins does the Teensy 4.0 have?
40 GPIO pins are exposed. Xirkit documents 54 board pins, 40 of them with pin-level electrical limits.
Are the Teensy 4.0 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 4.0 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 4.0?
Supply range 3–5.5 V. Power inputs: VIN (3.6–5.5 V), VBAT, VUSB.
How much does the Teensy 4.0 cost?
From $19.95 at www.adafruit.com (2 supplier offers tracked). Prices are observed unit prices before tax and shipping.
What are the Teensy 4.0 dimensions?
35.56 × 17.78 × 1.57 mm. A STEP model is available for enclosure fit checks.
Which interfaces does the Teensy 4.0 support?
gpio, interrupt, adc, pwm, can, i2s, uart, i2c, audio, spi, led, sdio, control, usb.
How do I program the Teensy 4.0?
Supported frameworks: Arduino (Teensyduino), Makefile / command line.
Where does this Teensy 4.0 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.
