Couldn't load pickup availability
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.
This kit includes the Teensy 4.1 Microcontroller board with a Teensy 4.1 Ethernet Kit. This kit has all the parts needed to connect to the Ethernet port on the Teensy 4.1. It includes an Ethernet MagJack, bare circuit board, ribbon cable assembly, 2 header pins, and a capacitor. DIY soldering is required to assemble the kit (the Teensy 4.1 board is fully assembled and tested).
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.
Technical Specifications compared to Teensy 4.0
Teensy 4.1 & 4.0 use the same IMXRT1062, so most technical specifications are the same.
