Hello…is there a board definition for Adafruit’s QT Py S3 with 2MB PSRAM? (link)

Seems like PlatformIO only has adafruit_qtpy_esp32s3_nopsram which points at adafruit_qtpy_esp32s3_nopsram and not variants/adafruit_qtpy_esp32s3_n4r2. However, it should be easy to add a custom board definition that uses that variant properly.

This worked great for me, thank you for the details!
Thanks for the confirmation, I’ve petitioned to add this board definition to the official repo per
Hello maxgerhardt - thanks a million for this. Works great.
The PR has been accepted, so you can equally use

folder. This should be included in the next stable version.
