c3 Zero

When using the ESPHome-Flasher everything seems to work and then I get an "invalid header"

I also tried the flash download tool, and while the flashing doesn't throw any issues, the board coms are just empty when connecting via cmd.
The LED also stopped working.

Could this be that I got the wrong c3-mini?
This is the one I ordered: https://www.amazon.com/dp/B0CS6VK6P7?ref=ppx_yo2ov_dt_b_fed_asin_title
While the listing says c3-mini the board says esp32-c3-zero on the back.

Got the esp home flasher to complete the flash but this is what it spits out in the logs:
Using 'COM4' as serial port.

After following what you guys did with the c3 mini super, I was able to get something working by changing uart num and pins (I modified the c3 mini super values:

#define UART_NUM UART_NUM_0
#define UART_TXPIN 28
#define UART_RXPIN 27

One of the bits I'm getting is:
␛[0;31mE (375) uart: uart_set_pin(723): tx_io_num error␛[0m
ESP_ERROR_CHECK failed: esp_err_t 0xffffffff (ESP_FAIL) at 0x420032e0
Not sure if this is an issue on the setup, or an issue with the board not wired up.

Changed tx to 21 and rx to 20. Those seem to be the correct ones.
That being said I don't really get much out of the logs now. A few lines and it stops:

Not sure if that means it's working or if there's something wrong...

[dlktdr]

That last log looks correct. Once connected to a radio via the rx tx pins you specified it should connect. If you change modes on the radio or connect to a ble device. You should see extra details in the log at that point.

[handcraftedcc]

Was able to get this one working by changing the tx and rx pin of the supermini. Could be cool to add it as build on here as it's a great cheap option.
