Designed for professionals and makers craving speed and versatility, it supports USB and Bluetooth connectivity, making it ideal for high-speed, complex projects that demand top-tier performance. ## Description The Teensy 4.0 is the latest Teensy, offering the fastest microcontroller and powerful peripherals in the Teensy 1.4 by 0.7 inch form factor. It features an ARM Cortex-M7 processor at 600MHz, with an NXP iMXRT1062 chip, the fastest microcontroller available today. Review: Powerful microcontroller with a cortex processor! - The Teensy 4.0 is a very powerful microcontroller with lots of customisation and other utilities. I got this as an overkill project for making a highspeed keypad (16Khz+ speed). In the future I may include a photo of the final result! Review: Good fast microcontroller. - If you've ever used an Arduino and want something faster then this is excellent, my old Arduino Nano runs at 16MHz but my Teensy is running at 600MHz, I can also overclock it 1GHz with a heatsink. I use it with the audio shield and am making a synthesizer. ## Features - Pre-Soldered Header Pins - System ram type: eeprom ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08259KDHY | | Best Sellers Rank | 104,757 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 409 in Microcontrollers | | Box Contents | 1 x Board | | Brand Name | Teensy | | CPU Model | Cortex | | Compatible Devices | Camera, Smartphone, Personal Computer | | Customer Reviews | 4.6 4.6 out of 5 stars (216) | | Manufacturer | PJRC | | Manufacturer Part Number | TEENSY40_PINS | | Memory Storage Capacity | 1 TB | | Model Name | Teensy 4.0 | | Model Number | TEENSY40_PINS | | Network Connectivity Technology | USB | | Operating System | DOS | | Processor Brand | ARM | | Processor Count | 1 | | Processor Speed | 600 MHz | | Product Warranty | 6 Months | | RAM Memory Installed | 1 MB | | RAM Memory Technology | DDR4 | | Total USB Ports | 2 | | UPC | 752785954244 | | Unit Count | 1.0 count | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** Teensy - **CPU model:** Cortex - **Memory storage capacity:** 1 TB - **Model name:** Teensy 4.0 - **RAM memory installed size:** 1 MB ## Images ![Teensy 4.0 (With Pins) - Image 1](https://m.media-amazon.com/images/I/615mqEg7TLL.jpg) ![Teensy 4.0 (With Pins) - Image 2](https://m.media-amazon.com/images/I/61h5GQmIVtL.jpg) ![Teensy 4.0 (With Pins) - Image 3](https://m.media-amazon.com/images/I/61TChXsHpcL.jpg) ![Teensy 4.0 (With Pins) - Image 4](https://m.media-amazon.com/images/I/615J4eKH33L.jpg) ![Teensy 4.0 (With Pins) - Image 5](https://m.media-amazon.com/images/I/51isTJy+bkL.jpg) ## Questions & Answers **Q: Does this has a microSD card slot soldered?** A: The 4.0 with pins does not have a microSD card slot soldered on it. **Q: Tiny and power. i see the micro usb connector but what are the other connector sizes/types. 2 pin? and 5 pin?** A: standard header dimensions. 0.100" ## Customer Reviews ### ⭐⭐⭐⭐⭐ Powerful microcontroller with a cortex processor! *by S***S on 11 March 2024* The Teensy 4.0 is a very powerful microcontroller with lots of customisation and other utilities.
