Just wanted to share a basic working config for this device (ESP32-8048S050) 
Heads-up: I try to keep the configs in these posts updated but sometimes the configs in my repo are more up-to-date!
Here are the device-specific bits of the config separated out from everything else:
esphome:
platformio_options:
build_flags: "-DBOARD_HAS_PSRAM"
board_build.esp-idf.memory_type: qio_opi
board_build.flash_mode: dio
board_upload.maximum_ram_size: 524288
esp32:
board: esp32-s3-devkitc-1
variant: esp32s3
flash_size: 16MB
framework:
type: esp-idf
# these versions prevent artifacting
version: 5.1.2
platform_version: 6.5.0
# Required to achieve sufficient PSRAM bandwidth
sdkconfig_options:
COMPILER_OPTIMIZATION_SIZE: y
CONFIG_ESP32S3_DEFAULT_CPU_FREQ_240: y
CONFIG_ESP32S3_DATA_CACHE_64KB: y
CONFIG_ESP32S3_DATA_CACHE_LINE_64B: y
CONFIG_SPIRAM_FETCH_INSTRUCTIONS: y
CONFIG_SPIRAM_RODATA: y
CONFIG_ESPTOOLPY_FLASHSIZE_16MB: y # fix warning about 2mb found

I like to keep device-specific code like that its own file separate from everything else so that I can use the Packages component to import it into multiple relevant projects, rather than duplicate the whole thing into each one. In my case I save it into a file called templates/ESP32-8048S050.yaml.
In the spirit of not duplicating code into multiple projects, I create another file that is not device-specific but is common/repetitive among all my projects. In my case I chose to call it templates/common.yaml and it has code like so:
esphome:
name: "${device_name}"
friendly_name: "${friendly_name}"
logger:
level: INFO
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
web_server:
port: 80
ota:
- platform: esphome
api:
Finally, this is how I use both of the above files together in a project.:
substitutions:
device_name: sunton-50-test-device
friendly_name: Sunton 5.0 Test Device
packages:
common: !include templates/common.yaml
device: !include templates/ESP32-8048S050.yaml
# dashboard: !include templates/dashboard_800x480.yaml
#sensor: ...
Note: The contents of the dashboard package referenced above aren’t in this post but I have it in the example to illustrate the power of setting up a config this way. In my case templates/dashboard_800x480.yaml is a file that I’ve created with HA sensors and LVGL pages in it, and it can be reused on any of my devices that support the same resolution as this one.
If someone wants to help get this device listed on devices.esphome.io then be my guest! I was too lazy to dig into that but hopefully posting here is just as helpful.
Concerns / Potential Improvements
- I suspect the framerate could be improved but I am not sure if that’s related to this config or not, and it’s only noticeable if you have animations or widgets that requrie scrolling.
