## Overview

The SparkFun Teensy 4.1 is a cutting-edge microcontroller board featuring a 600 MHz ARM Cortex-M7 processor with dual instruction execution, 8 MB flash memory, and 1 MB RAM. It offers extensive I/O options including Ethernet, USB host, and SD card support, plus advanced features like dynamic clock scaling and real-time clock with battery backup. Designed for professional-grade projects and rapid prototyping, Teensy 4.1 combines raw speed, versatile connectivity, and power efficiency in a compact, breadboard-friendly form factor.

## Description

Teensy 4.1 is the latest iteration of the surprisingly popular development platform that features a 600 MHz ARM Cortex-M7 processor, with an NXP iMXRT1062 chip, four times the 4.0 flash memory, and two new locations to optionally add more memory. The Teensy 4.1 has the same size and shape as the Teensy 3.6 (2.4in x 0.7in) and provides greater I/O capacity, including an Ethernet PHY, an SD card jack, and a USB host port. When running at 600 MHz, the Teensy 4.1 consumes approximately 100 mA of current and provides support for the dynamic scale of the clock. Unlike traditional microcontrollers, where changing clock speed causes incorrect baud rates and other problems, Teensy 4.1 hardware and Teensyduino software support for Arduino synchronization functions are designed to allow dynamically speed changes. Serial baud rates, audio stream sample rates, and Arduino functions like delay() and millis(), and Teensyduino extensions like IntervalTimer and elapsedMillis, continue to function properly as the CPU changes speed. Teensy 4.1 also provides a power shutdown function. By connecting a button to the ON/OFF pin, the 3.3V power supply can be completely disabled by holding the button for five seconds and back on with a short press button. If a coin cell is connected to VBAT, the Teensy 4.1 RTC also keeps track of the date and time while the power is off. Teensy 4.1 can also be overclocked, far beyond 600 MHz! The ARM Cortex-M7 brings many powerful CPU functions to a true real-time microcontroller platform. The Cortex-M7 is a dual-emission processor, meaning the M7 can execute two instructions per clock cycle, at 600 MHz. Of course, running two simultaneously depends on compiler order instructions and logs. Initial parameters have shown that the C++ code compiled by Arduino tends to achieve two instructions approximately 40% to 50% of the time while performing intensive numerical work using integers and pointers.

Review: greeat - I’ve been using this product for a few weeks now and I’m genuinely impressed with its performance and quality. The build is solid, it works exactly as advertised, and the setup was quick and hassle-free. The value for the price is outstanding, making it a smart choice for anyone looking to upgrade their toolkit or start a new project. I’ve tested it in multiple scenarios, and it consistently delivers great results. Whether for a hobby project or a more professional setup, it has earned a permanent spot in my collection. Highly recommend for its reliability, ease of use, and excellent value!
Review: Make sure to check product before throwing packaging away in case it doesn’t turn on. - I’m only giving this 4 stars because the first one I was sent was defective and just didn’t work. BUT they promptly went over a new one and it’s great, exactly what I was looking for!

### ⭐ Beware: Received Used and Damaged Product from SparkFun
*by S***R on 6 September 2025*

I bought a new Teensy 4.1 board, which was supposed to be new and sold by SparkFun on Amazon. When I received it, I was very disappointed to find that the board had already been used. Wires were soldered and then cut on several pins, and there were clear signs of use, which indicates this was not a new product. After removing the wires, I tried to make it work with a simple LED blink program. The board started to get hot, and nothing lit up, not even the power-on LED. The board seems to be defective. I paid for a new item and received a used, potentially damaged one. This is not the level of quality and service I expect from SparkFun. I am extremely disappointed with this experience. Buy with caution.
