The 8MB PSRAM Chip for Teensy 4.1 expands your Teensy 4.1 with an additional 8MB of RAM, ideal for memory-intensive applications and advanced embedded projects. This PSRAM chip can add 8 Megabytes of RAM for use on Teensy 4.1. 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. If 8 MB isn't enough, check out our 16MB PSRAM Chip for Teensy 4.1!
