Board request for Waveshare mini ESP32-S3FH4R2 (ESP32-S3-Zero Development Board)

[terrafirma2021]

Hi, can you please add support for the waveshare mini.

Thanks

Hi @terrafirma2021, usually a variant header file with proper pin definitions in the Arduino core is required to avoid frustrating issues when default pins (e.g. LED_BUILTIN) doesn't correspond to the real hardware.

In general, how do you know what sorts of things get added to that json file under ./boards? I purchased what looks to be this same board on aliexpress and I can't find much info about it beyond what was in the graphic on their product page.

Could it be the same board as this one: https://www.wemos.cc/en/latest/s3/s3_mini.html ?

It looks different, but has the same S3FH4R2 in it and seems to have the same specs:

based ESP32-S3FH4R2
2.4 GHz Wi-Fi
Bluetooth LE
4MB Flash
2MB PSRAM
27x IO
1x RGB LED (IO47)
ADC, DAC, I2C, SPI, UART, USB OTG

Though the LED is on GP21

Hi, can confirm that waveshare state to use on the IDE esp32s3.name=ESP32S3 Dev Module ( this is a generic board from what i understand, looking at the board info

But platformio does not support this native board by searching.

I did look on the website and it was mentioned to use the https://community.platformio.org/t/booting-up-esp32-s3-zero-cpu-start-octal-flash-option-selected-but-efuse-not-configured/37936

However, For me, I had a partition issue when i booted the esp, so my board did not accept the settings recommended.

E (75) spi_flash: Detected size(4096k) smaller than the size in the binary image header(8192k). Probe failed.

assert failed: do_core_init startup.c:328 (flash_ret == ESP_OK)

I have tried a few different solutions, but i am unable to get my board working with the platformio.

Ardruino IDE is fine, which I resorted to using for now, as my project only needed to send basic uart frames to my feather s3

@coryking Sorry i never reached back to you sooner, i decided to give the board another test on PIO. https://www.waveshare.com/esp32-s3-zero.htm You were spot on, thanks for replying, hopefully staff may add copy the config and add the name of the board, which will help out others who find this 5 usd board online and who want to use it without being limited to location of a pio file.

Can i suggest a name for the board as: waveshare_S3_Mini

PIO.ini: [env:lolin_s3_mini]

platform = espressif32

board = lolin_s3_mini

framework = arduino

monitor_speed = 115200

build_flags = -DARDUINO_USB_CDC_ON_BOOT=1

Note the built-in WS2812 pin on Waveshare S3 Zero is 21, while on Lolin it's 47

+1 on this request. I am facing issues with the same chip ESP32-S3FH4R2 on a similar board, the WeAct Studio ESP32-S3-Mini and I would like to know what settings are appropriate. Nothing works with Platformio, only with the Arduino IDE as commented by @terrafirma2021

Cheers

+1 for ESP32-S3FH4R2 and Waveshare S3 Zero there are more boards around with this chip https://www.lilygo.cc/products/t-micro32-s3 https://www.espressif.com/sites/default/files/documentation/esp32-s3_datasheet_en.pdf

For the ESP32-S3 FH4R2 please see https://github.com/sivar2311/ESP32-S3-PlatformIO-Flash-and-PSRAM-configurations?tab=readme-ov-file#esp32-s3-fh4r2

+1 for this one as well : ESP32-S3-Tiny (ESP32-S3FH4R2) RGB LED is on Pin 38

In PlatformIO i can make it work with this config :

[platformio]
name = ESP32-S3-Tiny
description = ESP32-S3-Tiny
default_envs = esp32

[env]
; Flash: 4MB QD, PSRAM: 2MB QD
platform = espressif32

board_build.arduino.memory_type = qio_qspi
board_build.flash_mode = qio
board_build.psram_type = qio
board_upload.flash_size = 4MB
board_upload.maximum_size = 4194304
board_build.extra_flags =
