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 solded to the smaller pads to be detected. If 8 MB isn't enough, you can solder 2 PSRAM chips for a total of 16 MB.
