## Overview

The PJRC Teensy 4.1 is a cutting-edge ARM Cortex-M7 microcontroller development board running at 600 MHz, equipped with 8 MB Flash and 1 MB RAM. It features an extensive I/O array including 35 PWM pins, 18 analog inputs, and multiple serial communication protocols. The included Ethernet Kit enables robust network connectivity, all within a compact 2.4 by 0.7 inch footprint, making it ideal for advanced embedded projects and rapid prototyping.

## Description

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.Teensy 4.1 & 4.0 use the same IMXRT1062, so most technical specifications are the same.

## Features

- ARM Cortex-M7 IMXRT1062 processor at 600 MHz, 1024K RAM (512K is tightly coupled) 8192K Flash (64K reserved for recovery & EEPROM emulation)
- Kit includes the Teensy 4.1 Ethernet Kit to connect to Ethernet
- 35 PWM Pins, 18 Analog Inputs, 8 Serial Ports, SPI, I2C, I2S,CAN Bus, IR modulator I2S (for high quality audio interface)
- 2.4 by 0.7 inch form factor, same as Teensy 3.6
