1. PJRC TEENSY 4.1-L Mikrocontroller Teensy 4.1 Lock
The Teensy 4.1 is a powerful microcontroller equipped with a 600 MHz ARM Cortex-M7 processor, known for its tremendous computing power and versatility. This version features a built-in Ethernet port for reliable and fast network connections, making it ideal for IoT and industrial applications. Additionally, the lock function provides the ability to permanently protect the firmware against reading and unauthorized access, making the Teensy 4.1 particularly suitable for security-critical projects and the protection of intellectual property.
2. PJRC Teensy 4.0, ohne Header
The Teensy 4.0 development board is a state-of-the-art microcontroller board equipped with an ARM Cortex-M7 processor, achieving an impressive clock speed of 600 MHz. It is based on the NXP iMXRT1062 chip, which is considered one of the fastest microcontrollers on the market. The board retains the same size and shape as its predecessor, the Teensy 3.2, and offers high compatibility with most pin functions. With a power consumption of about 100 mA during operation at maximum speed, it is suitable for a wide range of applications. Support for dynamic clock scaling allows for flexible adjustment of CPU speed without issues related to baud rates or other time-dependent functions. Additionally, the board features a convenient power shutdown function that can be activated with a simple button, and it maintains the date and time through a connected coin cell battery, even when the board is powered off.
- ARM Cortex-M7 processor with 600 MHz for high performance
- Dynamic clock scaling for flexible CPU speed adjustment
- Compatible with most pin functions of Teensy 3.2
- Power shutdown function via external button
- RTC functionality to maintain date and time when the board is powered off.
3. PJRC Teensy 4.1
It has the same size and shape as the Teensy 3.6 (2.4 x 0.7 inches) and offers greater I/O capability, Ethernet PHY, SD card socket, and USB host connection. When operating at full load, the Teensy 4.1 requires about 100 mA of power and supports dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed can cause incorrect baud rates and other issues, the hardware of the Teensy 4.1 and the software support for Arduino timing functions in Teensyduino are designed to handle dynamic speed changes without problems. Serial baud rates, audio streaming sample rates, and Arduino functions like delay() and millis(), as well as Teensyduino extensions like IntervalTimer and elapsedMillis, continue to work accurately even when the CPU speed is changed. The Teensy 4.1 also offers a power-off option. By connecting a push button to the On/Off pin, the 3.3V power supply can be completely turned off by holding the button for five seconds and turned back on with a short press. If a coin cell is connected to VBAT, the RTC of the Teensy 4.1 continues to keep track of the date and time even when the power is off. The ARM Cortex-M7 brings many powerful CPU features to a true real-time microcontroller platform. The Cortex-M7 is a dual superscalar processor, meaning the M7 can execute two instructions per clock cycle at 600 MHz. The simultaneous execution of two instructions depends, of course, on the compiler ordering instructions and registers. Initial benchmarks have shown that C++ code compiled by Arduino tends to execute two instructions about 40% to 50% of the time while performing numerically intensive work with integers and pointers. The Cortex-M7 is the first ARM microcontroller to use branch prediction.
