Adding a board: ESP32-S3-DevKitC-1-N8R8

I’m pretty new to PlatformIO, but I have managed to get my Lolin Lite board working. I just got a new board, the one specified in the topic. In the PlatformIO boards list there is one very similar but specified without PSRAM. I tried that one but I’m getting an error: ‘No serial data received’ when trying to upload. I was wondering if it’s simply the board that isn’t supported. And if so, how can I add this new board?

Here’s a link to the specific board:
ESP32-S3-DevKitC-1 v1.1 - ESP32-S3 - — ESP-IDF Programming Guide latest documentation
The N8R8 has 8MB OT PSRAM.

The same board was previously discussed in Suddenly PSRAM ID read errors... did a configuration file get corrupted? - #19 by maxgerhardt.
