Q:
It seems this board doesn't use CP210x USB to UART Bridge. I was not able to upload my code neither on MAC or on Linux (I tried using Arduino IDE, MicroPython and ESP-IDF). On Mac the device is recognized as /dev/tty.usbmodem* and on Linux /dev/ttyACM0. Do you guys have any advice?

There is a special usb driver for Mac available on the chinese website of the manufacturer of the chip.
Then there will be a second usb-device available wich has actually the ability to flash the esp.
