SparkFun MicroMod Teensy Processor with Copy Protection

SparkFun MicroMod Teensy Processor with Copy Protection

DEV-18771
$24.95

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).

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."

SparkFun Qwiic MultiStar Constellation Ornament

WIG-21277
$4.95

Have you ever had problems trying to daisy chain Qwiic-enabled boards with only ONE Qwiic connector? Or maybe you need a Qwiic-enabled device that is not in the middle of a daisy chain? The SparkFun Qwiic MultiStar adds five additional ports to boards that have only one Qwiic port on the I2C bus. Due to popular demand (and a few too many ordered), we have reworked the MultiStar into a working (and much safer) celestial version of the MultiPort with five Qwiic connectors. Once added, you can use it as a hub to add as many I2C devices to the bus as you need!


SparkFun Constellation MicroMod Kit

KIT-21224
$29.95

Now, if you want the full kit the the MultiStar is a part of, the SparkFun Constellation MicroMod Kit joins the ranks of the SkeleBoard and the SnowBoard. Instead of releasing a single board this year, we have opted to release a full kit, instead! This kit combines both MicroMod and Qwiic in a single box with a limited edition MicroMod ATP Carrier Board and MultiStar (this year's April Fool's Day joke). No, we aren't joking this time! Due to popular demand, we have reworked the MultiStar into a working (and much safer) celestial version of the MultiPort. Also included in this kit is a MicroMod Screw Driver and two Qwiic Cables to get you hooked up! The ATP Carrier Board and MultiStar included in this kit feature a matte black PCB with a star scape design in white silk.
