The new Teensy 4.1 has an ARM Cortex M7 processor with 600 MHz, an NXP iMXRT1062 chip, a flash memory four times larger than the Teensy 4.0 and two additional memory slots for memory expansion. It has the same size and shape as the Teensy 3.6 (2.4 x 0.7 inch) 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 approximately 100 mA of current and offers support for dynamic clock scaling.
