espD2WD, esp32D0WD chip development board

Develop test board for esp32 chip,

The board can weld the esp32D2WD model chip or the esp32D0WD chip + flash;

The chip size is 4*4 mm; it is difficult to solder and requires professional equipment and technology;

1.esp32D 2 WD model chip

Test the soldered esp32D 2 WD chip, the flash does not need to be soldered, the chip comes with 16 MB of memory and a 40 MB crystal oscillator;

To initialize the micropython firmware, you need to press and hold the button next to CH340C, and then power on again to directly upload the micropython code;

The c program of esp32arduino cannot be uploaded, and an error is reported when uploading. I don’t know how to solve it at the moment. If you know, please tell me;

The wifi has been tested and can be used within a distance of 10 meters;

2. esp32D 0 WD model chip
