## Description

This 8 MB PSRAM (pseudo-static RAM) chip adds extra memory to the Teensy 4.1 microcontroller board. Solder it to the smaller pads on the bottom side of the Teensy 4.1, underneath the SD card socket, between pins 31–32 and 33–34. A second PSRAM chip can be added for a total of 16 MB. In Arduino, use the EXTMEM keyword to allocate large arrays or variables in PSRAM. Note that EXTMEM variables are not initialised at startup and will contain random data — set them to zero or fill them before use. Key Features 8 MB PSRAM – Expands Teensy 4.1 memory for large buffers and data Stackable – Add a second chip for 16 MB total Arduino Compatible – Use the EXTMEM keyword to allocate variables in PSRAM Surface-Mount – Solders to dedicated pads on Teensy 4.1 bottom side Note: Use the smaller pads on the Teensy 4.1 bottom side (not the larger pads). Run the PJRC memory test program after soldering to verify proper operation. Ideal For Audio buffers and DSP applications Large data arrays and image processing Projects requiring more RAM than the Teensy 4.1's built-in 1 MB Package Contents 1× 8 MB PSRAM Chip
