Hi cederom, 1. Does that USB Serial/JTAG work with MicroPython? 2. Did anyone work with that port to Flash and REPL/CLI with the device? 3. If USB Serial/JTAG port works already, is it enabled by default or I have to rebuild MicroPython on my own to use that USB port not the UART0? 4. If USB Serial/...

Hi jhaand, ESP32-C3 (RISC-V) has a different memory layout than ESP32-S series (Xtensa), it should be flashed at address 0x0 instead of 0x1000. (I'm guessing 0x10000 in your post is a typo) I still see the following errors coming by after flashing to address 0x10000. I use a NodeMCU with ESP32-C3-32...

Just try to era...

One thing is that it does not mount as USB Storage Device and I cannot really edit `main.py` is there any other way to do that except edit from interpreter on the UART? :-) The easiest way I know is to use the Thonny IDE , it allows you to connect to REPL, transfer files to and from the microcontro...

What is the current status of MicroPython on ESP32-C3 chip? Is it production ready? :-) The release notes for v1.17 (latest stable to date) says "initial support for ESP32-C3 chips". If we look at the bugtracker , some peoples seem to have problems with I2C and BLE because of a timer issue. So I do...

I don't know if it is cheaper than your clone but still cheap (~5€).
I prefer it because it seems better quality and has more features like power switch, grove connector, D1 mini shields compatibility, functional RTS/DTR circuitry...

My pleasure. Are you good with the soldering iron? Beginners should practice before. Make sure the soldering tip isn't hotter than 370°C. The pads are tiny and the PCB is cheap. I use two soldering irons to remove parts. I am not doing too badly but I admit that I do not play too much with SMD part...

Good job, it should not have been easy to solder 0402 resistors!
Thank you for your feedback and for the firmware, I should try to do the same on mine.

New episode, I dug a bit and found the solution. First good news, the procedure above works like a charm to load MicroPython on ESP32-C3 :) My problem is the board does not have the proper circuitry to manage RTS & DTR when opening the serial port. This circuitry exists on the schematic of the docum...

Hello, I would like help to deploy a prebuilt MicroPython firmware on an ESP32-C3 board, for now it does not boot. The board I use is an AI Thinker ESP32-C3-32S_Kit with 4MB flash https://docs.ai-thinker.com/_media/esp32/docs/esp-c3-32s-kit-v1.0_specification.pdf I downloaded last esptool (3.1) that...
