ESP32 C3 super mini

[Oli]

Hello everyone,
I'm currently testing a great circuit board, ESP32C3 super mini 4MB flash
My problems started with the USB drivers,
I then found "Zadig", so far I only knew it for hacking of any cell phones, but it works great with the ESP USB. I found 2 unknown drivers, but now it is 1 Com interface. flashing and serial work well.

The board needs 90mA, gets a bit hot, it is very small for 0.5W.
Nevertheless, I think the energy consumption is good.

The sleep command works well
0.06mA needs when sleeping,
the red power LED resistor i remove,

Waking up: The timer RTC wakes up the IC perfectly for booting, I didn't need a bridge from the RTC to wake up pin.

Overvoltage, i try up to 4.2V on the 3.3V input for lithium, it works, the same courrent,
the 5V voltage regulator have drop only 0.4V and don't need courrent.


The RTC memory does not work properly, only the first 8 bit always really, then mostly data waste. (not always) in my case
BAS.RTCMEM$ = "successfully read from the RTC" becomes WLOG BAS.RTCMEM$ show: "successfúg" which I use via WLOG display, which then let the editor crash. Because of special characters. i dont need this, i write better to file,

The price is currently about € 2.50, I am very satisfied. the Wifi Range is good,
