Teensy 4.1 Development Board
The Teensy 4.1 is the newest iteration of the astoundingly popular development platform that features an ARM Cortex-M7 processor at 600MHz, with an NXP iMXRT1062 chip, four times larger flash memory than the 4.0, and two new locations to optionally add more memory.
The Teensy 4.1 is the same size and shape as the Teensy 3.6 (2.4in by 0.7in) and provides greater I/O capability, including an ethernet PHY, SD card socket, and USB host port.
When running at 600 MHz, this Teensy board consumes approximately 100mA current and provides support for dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed causes wrong baud rates and other issues, Teensy 4.1 hardware and Teensyduinos software support for Arduino timing functions are designed to allow dynamic speed changes.
Serial baud rates, audio streaming sample rates, and Arduino functions like delay() and Millis (), and Teensyduinos extensions like IntervalTimer and elapsedMillis, continue to work properly while the CPU changes speed.
Teensy microcontroller 4.1 also provides a power shut-off feature. By connecting a pushbutton to the On/Off pin, the 3.3V power supply can be completely disabled by holding the button for five seconds and being turned back on by a brief button press.
If a coin cell is connected to VBAT, this board’s RTC also continues to keep track of the date & time while the power is off. Teensy 4.1 also can also be overclocked, well beyond 600MHz!
Teensy 4.1s Cortex-M7 processor includes a floating-point unit (FPU) that supports both 64-bit double and 32-bit float. With M4s FPU on Teensy 3.5 & 3.6, and also Atmel SAMD51 chips, the only 32-bit float is hardware accelerated.
Any use of double, double functions like log(), sin(), and cos() means slow software-implemented math. The 4.1 Teensy development board executes all of these with FPU hardware.
