Adafruit has announced the availability of the PJRC Teensy 4.0 USB development board today making it available to purchase just under $20. The small 600 MHz microcontroller features an ARM Cortex-M7 processor at 600 MHz, with a NXP iMXRT1062 chip, the fastest microcontroller available today.
“The NXP iMXRT1062 is a ‘cross-over’ processor, which has the functionality of a microcontroller, at the speeds of a microcomputer. It’s perfect for when you need tons of flash, RAM and, to crunch lots of data, or when you need two full speed USB ports. It even has a graphics processor! All this for two sawbucks.”
