Teensy 4.1 Fully Loaded

Description

Includes 8MB PSRAM and 16MB Flash or 16MB PSRAM installed and tested with all pins soldered for a fully plug-and-play board.

Select which version you want and the quantity.

Note:  Teensy 4.1 are in short supply due to temporary limited availability of the NXP microcontroller.  We will try to keep a few Fully Loaded versions in stock as long as we have the base Teensy 4.1 in stock to build them with.  Additional stock will hopefully be available by early July.

Package Includes:

• Teensy 4.1 w/ PSRAM, Flash, header pins and ethernet header installed
• Handy pinout diagram

8MB PSRAM and 16MB Flash

The Teensy 4.1 has locations for optional 8MB PSRAM (SPI Serial RAM) and 16MB Flash (SPI Serial Flash) memory chips that can be installed by the user.  These surface mount locations can be difficult to solder and many technical issues are eventually traced back to poor soldering on these components.

For those wanting these parts without the drama, we are offering a fully populated Teensy 4.1 with these chips preinstalled and tested.

In addition, all the other normal soldering like the selectively plated gold header pins is completed.  We also add a gold plated 2×3 2mm Ethernet header for use with the optional Teensy 4.1 Ethernet kit since it is easiest to add it before adding the headers, thus making it fully ready to plug-n-play.

16MB PSRAM

Once assembly is completed, we run test software which is a combination of the PJRC PSRAM and Flash test programs that thoroughly exercises these devices.

If you prefer, we can also build the board with a second PSRAM chip in place of the Flash chip for a total of 16MB of PSRAM and no Flash.  Price is the same for either version.

If you are working with ethernet, we also have a fully assembled ethernet port kit available as well.
