SparkFun MicroMod Teensy Processor with Copy Protection

Added to your shopping cart

The SparkFun MicroMod Teensy Processor with Copy Protection leverages the awesome computing power of the NXP iMXRT1062 chip and pairs it with the M.2 MicroMod connector to allow you to plug it into your choice of compatible MicroMod Carrier Board. This "copy protection" variant comes with additional security that can be applied for commercial products and secure applications. With the M.2 MicroMod connector, connecting your Teensy Processor is a breeze. Simply match up the key on your processor's beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all Carrier Boards). Adding a Teensy to your desired project has never been easier!

The SparkFun MicroMod Teensy Processor with Copy Protection utilizes the same hardware as the "Lockable" Teensy from PJRC. When discussing MicroMod Teensy with SparkFun customers, we have seen two fairly distinct patterns. Entrepreneurs care about keeping their firmware from being copied by competitors and the process of permanently locking secure mode can be mentally stressful. So we updated the name to better emphasize the primary customer benefit; "copy protection." When compiling, your program is encrypted. When run, the IMXRT Bus Encryption Engine provides on-the-fly decryption as your program executes. If an attacker removes and reads the flash memory chip from Teensy 4.1, attempts to capture the USB communication from Teensy Loader, or copies the EHEX file Teensy Loader opens, they get only an encrypted copy of your program.

The Teensy Processor Board boasts some impressive computing power with an ARM Cortex-M7 processor operating at clock speeds up to 600MHz, 16MB Flash Memory and 1024K RAM Memory. On top of all that processing power, the board features seven serial UART ports, four I2C buses, two SPI ports, CAN-Bus, 12 GPIO, dedicated digital, analog, and PWM pins, USB Host and Device capability up to 480Mbit/s, digital audio and since many of the pins on the iMXRT1062 support multiple signal types you can customize it even further depending on your project's needs.

Teensy is a registered trademark of PJRC. The MicroMod Teensy is a collaboration between PJRC and SparkFun.


MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

Dive into the world of MicroMod - a compact interface to connect a microcontroller to various peripherals via the M.2 Connector!

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels


Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
