Otherwise, if they use 5V or higher voltages, it may (highly probable) destroy your ESP32 I/O (Input-output) pins and make the part useless. You can use other USB to Serial port converters as long as they operate in the range of 3V - 3.3V. Once the previous step was successfully completed, we can continue with the hardware setup/wiring or interconnecting the cables between the ESP32-WROOM and the USB to Serial port converter, which is the programmer. Once you have completed adding support for the ESP32, feel free to continue. If you are not sure what it is and how to do it, make sure you visit one of the following links, depending on what operating system you use. You can find it here.īefore you start, ensure you have successfully installed the Arduino programming software and added ESP32 support to it. If you ask yourself how to solder the ESP32-WROOM-32, I made a tutorial earlier. The list of parts used in this tutorial are:ġx USB to Serial port CP2102 – you can get one here.ġx ESP32-WROOM-32 (also known as ESP32-F) with PCB for it – you can get one here.ĥx Dupont wire, female on both sides – you can get a set here. I hope it will be easy to follow and you will be ready ASAP to try out your ideas. Two short clips, each less than 3 minutes, were recorded to ensure no mistakes are made and the magic smoke does not leave your electronic devices. At some or another point I will forget the setup myself and this guide will hopefully save me some time and get me up to speed. Since I had some free time, I made a step by step guide/tutorial on how to program the ESP32-WROOM-32 with the Arduino software.
