I just received one and cannot install it in ESPhome
Have you received yours ? where have you ordered from ?
(me PiHut … a uk based shot and I received some customs fees cause I’m EU based 
)
I’ve posted here :
I’ve used a couple of the Picos them. The C3U is on the shelf, I hope there are no bigger issues setting them up with ESPHome. I wanted to try these days.
M5Stamp Pico (no big surprise here):
esphome:
name: test
platform: esp32
board: pico32
That’s the C3U I’m struggeling with
Even it’s the first time I’m ‘playing’ with those kind of boards
I’m not sure I’ll buy C3U any more
Thx for that quick reponce.
Any one buying from amazon ?
I’ve seen a lot of Ebays, Ali Express
What do you think about this one for eg :
https://www.amazon.fr/gp/product/B08BTRQNB3/ref=ox_sc_act_title_1?smid=A1X7QLRQH87QA3&psc=1
I just ordered from https://thepihut.com/ and had some big customms fees (uk shop and I’m EU based)
fees were 25€ out of a 50€ order :’(
I grouped a few names seen on this post.
Lolin seems to have succes but not all supported and long delivery time from what i see.
LILYGO® TTGO T7 V1.5 Mini32 also on aliexpress seemed to have more then one good review here !

I have a M5stack STAMP-C3U > first time playing with those but I’m struggeling
Really, we can’t see your cart on amazon.
I’ll try later this week. Based on these resources:
I would expect a config like this (untested! probably not working):
esphome:
name: test
platform: ESP32
board: esp32dev
platformio_options:
platform: espressif32
board: esp32-c3-devkitm-1
board_build.mcu: esp32c3
board_build.f_cpu: 160000000L
upload_protocol: esptool
build_flags:
- -D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC
- -D USBCON

hahah sorry
link updated
By the way… with the help of radybb from esphome discord I got my M5stack STAMP-C3U working.
It had something to do with my newbie state more than a board problem.
He also shared this good EU site for ordering without any custom fees : https://www.distrelec.de
Good for you but would you please share your working solution? Thanks, appreciated!
sure 
M5stack STAMP-C3U
HAOS running on raspbery pi 4
At the moment basic board config seem working.
I’m still trying to add sensor for ‘Bt low energy bridge config’
https://xoops.hypweb.net/modules/UsersWiki/person/nao-pon/blog/2021-03-17
press central button while plugging board to HA server
this is my yaml (not sure all is needed, because build after lots of test) :
esphome:
name: bluetooth-low-energy-bridge
platformio_options:
board_build.flash_mode: dio
platform_packages:
- toolchain-riscv32-esp @ 8.4.0+2021r1
- toolchain-xtensa-esp32s2 @ 8.4.0+2021r1
esp32:
board: esp32-c3-devkitm-1
variant: esp32c3
framework:
type: esp-idf
logger:
hardware_uart: USB_SERIAL_JTAG
i hope this will help
One of the ESPHome Devs mentioned on Discord that support for a lot more variants will come with the 21st Dec release and are now available in the dev branch.

Do you happen to have the IO’s used for relay, buttons and and LED’s for this board?
Hello, I’ve too many boards and projects in my lab. If you can specify what board you are interested in, I will see if I have some notes that will be of use.
Was able to print some of my own with my label maker. Might be able to get the quality a bit better but they do the job.

I hope this improves general performance of Lolin S2 Mini.

Hello @dproffer, I’ve just received one board like the one in your link:
Right now, I have working Relay (GPIO16), Button (GPIO0), Led (GPIO23), but I’m struggling to configure a DHT temperature sensor in Esphome. If I choose GPIO25 or other similar pin, the temperature sensor doesn’t work,
[14:12:11][W][dht:169]: Requesting data from DHT failed!
[14:12:11][W][dht:060]: Invalid readings! Please check your wiring (pull-up resistor, pin number).
But if I configure the temperature sensor in GPIO23 (the one assigned to the LED) the temperature sensor starts reporting data.
This is my current “working” configuration:
substitutions:
upper_devicename: termostato_multi
esphome:
name: termostato-multi
platform: ESP32
board: nodemcu-32s
switch:
## Relay
- platform: gpio
pin: GPIO16
name: ${upper_devicename} relay
id: relay
binary_sensor:
## Boton 1
- platform: gpio
pin:
number: GPIO0
inverted: true
name: ${upper_devicename} button_01
id: button_01
on_press:
- switch.toggle: relay
## LED
output:
- id: led_output
platform: gpio
pin: GPIO23
light:
- platform: binary
name: ${upper_devicename} led
id: template_led
output: led_output
## Sensor temperatura
sensor:
- platform: dht
model: AM2302
pin:
# inverted: true
number: GPIO25
mode: INPUT
temperature:
name: ${upper_devicename} temperature
id: temp_room
humidity:
name: ${upper_devicename} humidity
id: humidity_room
update_interval: 60s
Did you manage to get working any other exposed GPIOs?
In other terms, I am thinking to use the board as thermostat inside my wall. Have you done something similar or have you had a negative experience that makes me give up the idea?
Thank you!
Daniel
Hi Daniel,
I did not work with this board in ESPHome, but only with native ESP tools. And I never went beyond basic I/O code. So I cannot be of much help. You might try simple I/O on the pins you are using and check with logic analyzer to see if you might have a bad solder joint to the lead out. Also compare and contrast with a naked ESP32 board of you have one. The devices I received seem solid, no issues that I remember, I have yet to put one in any production app as yet. As to whether it is a good idea to put in wall, you could look back through this discussion thread to see peoples opinions on safety. Good hunting!

For further support on it, please create a new topic. Cheers.

Thank you very much for your fast and specific answer!
Apparently I have it working now, my fault, poor soldering prevented good contact on a pair of pins.

I checked the QuinLED and for European buyer, pay attention that AllNetChina is not declaring VAT. Therefore you will be charged extra fees + VAT when coming to your country.
I did not find any other store that are selling the QuinLED so I don’t think they are an option for european citizen (or at a very high cost compare to other possibilities).
If anybody knows a place where I can buy it from EU, please let me know
