Teensy 4.1 iMXRT1062 Microcontroller Development Board by PJRC
With and Without Ethernet Option
NOTE: Due to shortages and price increases on the Ethernet PHY chip, the Teensy 4.1 microcontroller is now being offered both with and without Ethernet capability. The type (with or without the Ethernet chip on the board) can be chosen at checkout.
Teensy 4.1 is the latest Teensy microcontroller development board from PJRC. It features an ARM Cortex-M7 IMXRT1062 processor at 600 MHz. The actual size is 2.4 by 0.7 inch, the same form-factor as Teensy 3.6.
Teensy 4.1 uses the same processor as Teensy 4.0, but provides greater I/O capability, including an ethernet PHY, SD card socket, and USB host port. Teensy 4.1 also comes with 4X larger flash memory, and has 2 locations to optionally add more memory.
