Teensy 4.0 is the latest Teensy microcontroller development board from PJRC, based on the most powerful microcontroller available today, the NXP iMXRT1062 ARM Cortex-M7 running at 600MHz with the ability to be overclocked. It is designed into a very compact ‘Teensy’ board outline of 1.4 by 0.7 inch (3.6 x 1.8 cm) for easy embedding into projects or for use with solderless breadboards. Teensy 4.0 is the same size and shape as the Teensy 3.2 and retains compatibility with most of its pin functions.
Teensy 4.0 is compatible with the Arduino IDE programming environment as well as many of the existing Arduino libraries, so it is easy to get programmed and running, unlike other advanced microcontrollers on the market.
This Teensy 4.0 from Envistia Mall includes a 40-pin male header that can be broken or cut to the appropriate length using a wire cutter or pliers and soldered onto the microcontroller, giving you the flexibility to choose how to connect the Teensy to your circuitry.
This is the LOCKABLE version of the Teensy 4.0. can be permanently locked into a secure mode. This implements encryption of the software and prevents unauthorized copying or cloning of the software. This version is identified with a lock symbol stamped on the CPU. This lockable version will operate like a standard Teensy 4.0 if it is not locked, but it removes some of the safeguards that are built into the standard Teensy 4.0 to prevent permanently bricking the module with bad software. For this reason, it is recommended fir use only when code security is a requirement, usually for commercial applications. When code security is not required, we recommend the standard non-lockable version.
