Awesome Extras
Teensy 4.1 with Ethernet features the fastest microcontroller and an expanded set of powerful peripherals in a 2.4"x0.7" form factor and can be programmed using the Arduino IDE with Teensyduino add-on.
This version has the pin headers pre-assembled - great for those who don't enjoy soldering. We also stock the standard unassembled with Ethernet version which comes with free separate pin header strips.
Comparison to Teensy 4.0
Teensy 4.1 & 4.0 use the same IMXRT1062, so most technical specifications are the same. Please refer to the Teensy 4.0 page 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.
Ethernet
To use the Ethernet port, a magjack and capacitor need to be connected.
We have the PJRC Ethernet kit available here.
Memory Expansion
The bottom side of Teensy 4.1 has locations to solder 2 memory chips
The smaller location is meant for a PSRAM chip. The larger location is intended for flash memory.
The PSRAM chip is meant to be soldered to the smaller pads on the bottom side of Teensy 4.1, underneath the SD card socket, between pins 31-32 and 33-34. Do not use the larger pads. A single PSRAM chip must be soldered to the smaller pads to be detected.
USB Host
Teensy 4.1's USB Host port allows you to connect USB devices, like keyboards and MIDI musical instruments. A 5 pin header and a USB Host cable are needed to be able to plug in a USB device. USB hubs may be used if more than 1 device is needed.

Teensy 4.1 with Ethernet (Headers)
Teensy is a great piece of kit and full deserves the 5 stars, but..
I always buy the unsoldered (without headers). I ordered 3 of these as unsoldered were out of stock, and all headers were misaligned. Two of them have caused me a lot of trouble (disconnects and hangs as if poor power contact) and I might just return them rather than try to sort their issues. Do yourself a favour, buy the unsoldered ones and solder yourself (also, it's just the main headers that are soldered - ethernet, USB etc are unsoldered).
I've bought dozens of Teensy 4.1 unsoldered, and never had an issue with a single one until these soldered ones turned up. Disappointing to say the least.

Arrived even faster than promised, exactly as ordered. There is a good reason I am a frequent return customer.
