Hey!
Can you provide a hardware revision history for the board?
I bought some BPI Leaf S3 from some distributors and one was 1.0 and one 1.1. I couldn't find information about what the differences are.
Thank you!

Hello

can you give me for the ili9341 display a fast example with a fast library in micropython.

Greetings

command:
python -m esptool --chip esp32s3 --port COM11 --baud 921600 write_flash 0x0 BPI-Leaf-S3_MicroPython_v1.19.1.bin

error:
Writing at 0x000126a9... (3 %)Traceback (most recent call last):
File "", line 198, in _run_module_as_main
File "", line 88, in _run_code

Please help me writing a small arduino sketch that monitors the voltage of the battery connected to the bpi-leaf-s3.
I'd like to see he voltage on a small oled and when the voltage is below a certain value (for example 3.7V) the leaf should go into deep sleep.
What pin should be read? what multiplication is needed to give a good value?
I tried A13 but am not happy yet. :)
And if there is a better place to ask - please let me know.
Thank you and best regards!

According to the datasheet, the LDO I see on the schematic - SY8089AAAC - features quiescent current of 50uA (https://www.olimex.com/Products/Components/IC/SY8009A/resources/SY8089AAAC.pdf, page 4). Your advertised deep sleep current of 10uA seems unrealistic. Can you please confirm that 10uA is current drawn from the connected LiPo battery when the ESP32-S3 is in deep sleep?

Hey!
Is/Can you make the firmware of this board open source?
I only saw the firmware in binary format in this repository.

Using BPI PicoW S3 (BPI Leaf S3 board selected) I have no activity from Serial Monutor; only one String "ESP-ROM:esp32s3-20210327" Sketch was from Arduino IDE 2.1.0 (ESP32 2.0.8 Board core); Example>ESP32>Deep Sleep>TimerWakeUp.ino.

Screen Capture showing device manager, Windows 11.

Also, pressing RESET button loses comm port; have to short boot pad to get comm port back.

Device manager>Ports>Properties>Events: Device USB\VID_303A&PID_1001&MI_00\9&72ab14a&0&0000 requires further installation.

Could you please update board schematics?
