PJRC Teensy 4.1 ARM Cortex-M7 Microcontroller + 2X 8 MByte PSRAM SOIC ICs

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 two 8 MByte PSRAM SOIC ICs. It has all the parts needed to add 16 Megabytes of RAM to the Teensy 4.1.

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.

Please refer to the for common specifications and features.

Pinouts

Teensy 4.1 is designed to bring all general purpose I/O pins to breadboard friendly pads on the outside edges.

Note: The Teensy 4.1 does not include headers and, if needed in your application, and soldered on yourself.

Package Includes:

1x PJRC Teensy 4.1 Microcontroller Development Board without pins
2x (2 Pieces) 8 Megabyte PSRAM SOIC Chips
Printed pinout and usage reference card

NOTE: The SOIC PSRAM chips are not soldered onto the Teensy 4.1 board. The user will need to solder the chips to the Teensy board in order to use them. See the PJRC Teensy 4.1 website for detailed instructions.
