The Teensy 4.1 is the newest iteration of the astoundingly popular development platform from PJRC. It features an ARM Cortex-M7 processor at 600MHz, with a 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.
Note: Please be aware that the Teensy 4.1 does not include headers and will need to be purchased separately and soldered on yourself. Teensy 4.1 Without Ethernet does not have the ethernet PHY chip.
