If you are looking for a Teensy 4.1 fully loaded for use with a PCB baseboard that requires the I/O to be brought out from the bottom of the Teensy 4.1 like for use with our Prototyping System or Project System for Teensy 4.1 baseboards, head over to this link: https://protosupplies.com/product/teensy-4-1-fully-loaded-for-prototyping-system/ Please Note: We keep a small number of each version of the Teensy 4.1 in stock for immediate shipment. Since this item is hand-modified, if you need more than what we show in stock, the website will allow you to backorder the quantity that you need. Back-ordered Teensy 4.1 will typically ship within 1 to 2 business days. If you need a large number or require further customization such as being built with the Lockable version of the Teensy 4.1, adding the VIN/VUSB blocking diode or adding the USB Host header, email us at [email protected] with your requirements. Package Includes: Teensy 4.1 configured with PSRAM and Flash memory based on selection, header pins and ethernet header installed Handy pinout diagram The Teensy 4.1 has locations for optional PSRAM (SPI Serial RAM) and 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. This is especially true of the WSON Flash memory packages. The Ethernet header can also be a little difficult to install. For those wanting these parts without the drama, we are offering 7 standard versions of the fully populated Teensy 4.1 with these chips preinstalled and tested. DEV-24-B (Bare with No Added Memory) has just the male Ethernet header installed along with standard pins, but no additional memory is installed.

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. 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. The memory are tested at an elevated 120Mhz bus rate. The current QSPI bus speed is 105.4MHz. If you are working with ethernet, we also have a fully assembled ethernet port kit available as well.

Choosing between 8MB vs 16MB PSRAM Chips The obvious difference is that the 16MB PSRAM chips have twice the memory capacity, but they also cost more than the 8MB parts for the same amount of memory. If you are wanting to push the performance of the PSRAM by increasing the QSPI bus speed from the default 105.6MHz (as of Teensyduino 1.60 Beta 5), the 8MB parts can be pushed harder and will run at up to 166MHz in our testing. The 16MB parts on the other hand can only handle about 120MHz when 2 of the chips are installed. The 16MB parts use two 8MB dies internally, so they load the QSPI bus more than the 8MB parts which may account for the speed difference. If a Flash chip is installed instead of a 2nd PSRAM, the 8MB PSRAM parts are limited to 132MHz due to the slower Flash installed on the same bus. The 16MB will still operate at 120MHz when coupled with a Flash chip. Support for the 16MB PSRAM is included in the core Teensyduino as of version 1.60 or newer. Be sure to upgrade to the latest version before trying to use these chips. http://forum.pjrc.com/index.php?threads/teensyduino-1-60-released.77695/ Before they are shipped, the Teensy 4.1 has: Memory is configured as selected above.
