We don't typically release blog posts on Monday unless there is something special or extroraordinary to announce. Well, guess what? Today, we are thrilled that the new Teensy 4.1 has been announced by PJRC, and SparkFun will be carrying it!

The product page for the Teensy 4.1 is up and available for pre-order, and we expect to have the board in by this afternoon. We will update you as we receive new information, but as far as we have been informed physical stock will arrive today. Orders will be fulfilled in the order they are received so if you want one, make sure to get your order in now!

Teensy 4.1

Teensy 4.1


The Teensy 4.1 is the newest iteration of the astoundingly popular Teensy development platform. It features an ARM Cortex-M7 processor at 600MHz with a NXP iMXRT1062 chip, four times more flash memory than the 4.0, and two new locations to add more memory if needed. The Teensy 4.1 is the same size and shape as the Teensy 3.6 (2.4 x 0.7 in), and provides greater I/O capability including an Ethernet PHY, microSD card socket, and USB host port.

We will go into more detail on the 4.1 this Friday with our regular product post. Let us know what project you plan to make with the newest Teensy in the comments below, shoot us a tweet @sparkfun, or let us know on Instagram or Facebook. We love to hear ideas!

Never miss a new product!

    Yay! Another product with a true Real Time Clock Calendar! ;-)

    (At the moment, I'm still recovering from my broken leg, so probably won't be ordering one for a few weeks...)

      Hopefully the broken leg is on the clock/calendar chip!
