Prepare ESP32
After that, let's adjust our board in Arduino IDE.
| Setting | Select | Note |
|---|---|---|
| Board | ESP32 Dev Module | Use your board. Not sure if it works on other, too |
| Upload Speed | 921600 | 921600 may unstable while upload. 115200 takes minutes |
| CPU Frequency | 240MHz (WiFi/BT) | Lower Clock heavily decrease speed |
| Flash Size | 4M (32Mb) | 4MB = for Flash |
| Flash Mode | QIO | Doesn't matter |
| Flash Freq. | 80MHz | Doesn't matter |
| Part. Scheme | Huge APP (3MB No OTA) | You don't need WiFi/BT for this |
| Core Debug Lv | "none" | We won't use Serial at all, becaus performance impact |
| PSRAM | "Disabled" | We don't need it |
| Port | Port of your ESP32 | For the first use, select COM X of the ESP8266-XX |

Plug your board via the built-in USB port to your Computer and wait until the driver is installed. If you get an error something like no driver available, you need to download one from the Internet. Note! There are two kinds of driver for ESP32!
| Chipsize near USB Port | Company | Clone | Driver |
|---|---|---|---|
| A big rectangular one | LoLin etc. | Yes | CH34X |
| A little squar one | Silicon Labs | No | CP210X |
Left LoLin, right Silicon Labs. Photo Source (Picture for ESP8266, but similar to ESP32 about the chip size)
After plug-in, choose the port in Arduino IDE. If you're not sure which port you ESP32 is taking for, just search/open on Windows "Device-Manager" and look for "...(COM & LPT)". They should something like "CP210X" or "CH34X" listed with port number.
