Thanks for your input Esp_sprite, I was unaware of the DRAM-capable psram interface on the S3-model. In fact, a new S3 unit just arrived last week! So now I have a very good reason to start playing with it soon! I'm using mrfaptastic's HUB75 ESP32 I2S DMA library. You don't happen to have any experi...

Thank you WiFive for clarifying that.

My project is driving LED Matrix panels, for which I need DRAM-capable SRAM.

Are there any tricks to increase the amount of available sram on the databus?

Or do you know if there are other espressif chips which expose more sram?

Hi, Does anyone know an ESP32 board which has more than 320KB of SRAM? I've tried various brands and models, some of them announcing they have 512 or even 520 Kb of SRAM, but have not found a board which has more than 320 Kb of SRAM. Is the 320Kb a hardware limit of some kind on the ESP32 chip? I ha...
