I have a Wemos Lolin ESP32-S3 Mini V1.0.0 (S3FH4R2) and I am not able to install esphome on it, I have tried with many of the configurations that appear in this forum, both with arduino framework and with ESP-IDF.
If anyone has this board working with esphome and can share the configuration file I would be very grateful or any suggestion would be welcome.
Thanks.

thanks.
working when compiled on esphome dev branch.
This configuration worked for me,
name: ${host_name}
friendly_name: ${upper_device_name}
platformio_options:
board_build.flash_mode: dio
board_build.extra_flags:
#- "-DARDUINO_USB_MODE=0"
- "-DARDUINO_USB_CDC_ON_BOOT=0"
esp32:
board: ${board_type}
framework:
type: arduino
Although I can’t remember now if to get the initial flash I had do the hold the 0 button whilst reseting, but after that all operations carried out over WiFi.
Oh and don’t forget to add the output_power limit,
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
output_power: 10
I’m able to compile and upload with the code below but I’m getting an error in the logger and it’s not booting.
Error is below
INFO Successfully uploaded program.
INFO Starting log output from /dev/cu.usbmodem1101 with baud rate 115200

Any ideas about what could be happening? Thanks!
Here’s a config that worked for me. It turns out support for the Lolin S3 Mini was only added to platformio recently, so you need to specify some more recent versions of packages than the default ESPHome config provides. The platformio_options are merged from a collection of several posts I found here and elsewhere. I’m not sure these are all needed.
Important: when flashing over USB, I noticed that the S3 Mini doesn’t always reboot itself after the flash process completes. I had to manually press the RST button and wait a couple of seconds for it to reboot and join the wifi.

I am brand new to ESPHome and I got a few of these little Wemos Lolin S3 Minis and was hoping to use them for this Digiblur mmWave presence sensor project (minus the humidity sensor as I don’t need it where I’m placing these sensors): This DIY mmWave Presence Sensor Changed Everything - LD1125H How To Guide | digiblurDIY.
Digiblur’s code seems to leverage Patrick’s code from here: https://github.com/patrick3399/Hi-Link_mmWave_Radar_ESPHome/blob/797b2d1334f5c6b75e2e1e887e03e395a1ab5092/LD1125H/ESP32-LD1125H-Complete.yaml.
All of the linked code makes use of a nodemcu-32s board, so my assumption was to change it to “lolin_s3_mini” but I have not had any luck getting the code to compile. I’ve then tried appending the esphome section to some of the examples provided above in the thread but I unfortunately have not had any success.
Is anyone able to shine some light on this?
Solved, my own problem: I was finally able to figure out a solution and now I have the mmWave sensor working in my HA/ESPHome. The key for me was getting the framework to work using “version: latest”. Hope this helps someone else out!

Thanks for this, got me going!!
thanks!! I got this to work but had to change the flash mode back to qio
Tried all the other configurations I could find and couldn’t get anything to work.
Thanks, just tried with S3 mini, C3 mini and C3 pico and it works.
I changed
board: lolin_c3_mini
for both c3 mini and c3 pico which share the same chip.
Thanks! I had to use version 5.1.2 instead of latest to get it to build but now everything works!

Can someone please help ? I have Lolin ESP32 s3 mini .
I want to get on-board LED [Pin 47] (WS2812B) to work.
Can someone please share the configuration using arduino framework that compiles and works ?
