Key Features:
- Designed to bring all general purpose I/O pins to breadboard friendly pads on the outside edges
- Ethernet Option
- Can be programmed using the Arduino IDE with Teensyduino add-on
- ARM Cortex-M7 brings many powerful CPU features to a true real-time microcontroller platform
- Pins not included
Teensy 4.1 features the fastest micocontroller and an expanded set of powerful peripherals in a 2.4 by 0.7 inch form factor. It's designed to bring all general purpose I/O pins to breadboard friendly pads on the outside edges. Additionally, the bottom side of Teensy 4.1 has locations to solder 2 memory chips.
Item SpecificsSize: 2.4" x 0.7"ARM Cortex-M7 processor at 600 MHzTo use the Ethernet port, a magjack and capacitor need to be connectedRecommended Accessories (not included): USB Cable, Pins 24x1 (2), 8MB PSRAM, USB Host Cable, Ethernet Kit

Teensies are fantastic boards for projects that need a high clock speed unfortunately to make a Teensy an Xbox 360 controller third party libraries will be needed as the default framework hardcodes preselected USB description headers for specific devices. I needed a way to switch from one USB descriptor to another when sending a disconnect command out and I still haven't been able to use this device for that purpose however less dynamic USB connections work fine.

Works perfectly for me! Although it was a little more expensive than buying from other places, it worked perfectly!

Both products together make experimentation in audio processing a great experience.

if you are familiar with the Arduino concept and can program a bit this device is a must... set up a jig to hold you headers and solder them yourself... the teensy 3.5, 3.6, 4.0, 4.1.. wow Wow WOw WOW..... there is no other description for what these devices can do.....the 4.1 using simple digitalWrite HIGH low one can generate 30 nsec pules on that pin, and it can by coding be made faster... writing code to control the logic lines of interfaced chips is possible, SPI and I2C channels also exist not to mention the A/D capabilities..you will need to download the extension to the Arduino IDE and learn the new form of the A/D convert call...in the picture the teensy 3.6 and 4.1 are in setups. the scope picture shows the adj resistance X9C104 being changed it is is series with a 10k to Vcc.. i think it was 10k.... the time expanded pic show the timing detail.. i have delayMicrosecond(10 in the pulse generation code...learn to code.....!

Not available with pins anymore, apparently. VERY time-consuming to solder in on your own. Not good customer focus.

Works well with tons of memory left.

This small microcontroller has tremendous power to execute code. It runs at 600 MHz and has an instruction set that is hyper fast! If you feel the need for speed this is your MCU!

Perfect for Synth and MIDI projects. Amazing upgrade from Arduino microcontrollers. I would be nice if it was a 5 volt device, instead of 3.3. but so far it hasn't been a problem for me. Great product!
