GENERAL INFORMATION
Dear customer,
Thank you for purchasing our product. In the following, we will show you which
things should be noted during the use.
Should you encounter any unexpected problems, do not hesitate to contact us.
OVERVIEW
The NodeMCU ESP32 module is a compact prototyping board and is simple to program via the Arduino IDE. It has a 2.4 GHz dual mode WiFi and a BT wireless connection. Moreover, the microcontroller has integrated: a 512 kB SRAM and 4 MB memory, 2x DAC, 15x ADC, 1x SPI, 1x I²C, 2x UART. PWM is activated at all digital pins.
An overview of the pins can be found in the following picture:
INSTALLATION OF THE MODULES
If Arduino IDE is not already installed on your computer, first download this programm and install it. After that download the updated CP210x USB-UART driver for your operating system and install it. As the next step, you have to add a new board manager. For that follow the following instructions.
1. Click on File → Preferences
2.
Add to the Additional Bords Manager URLs the following link:
https://dl.espressif.com/dl/package_esp32_index.json
You can divide multiple URLs with a comma.
3. Now click on Tools → Board → Boards Manager…
4. Install esp32 by Espressif Systems.
The installation is now completed. You can now choose in Tools → Board the ESP32 Dev Module.
Attention! After the initial installation, tha board rate may have changed to 921600. This could cause problems. In such a case, set the baud rate to 115200 to avoid any problems.
USAGE
Your NodeMCU ESP32 is now ready to use. Simply connect it with an USB cable to
your computer.
The installed libraries provide many examples to gain you some insight into
the module.
These examples can be found in your Ardunio IDE in File → Example → ESP32.
The fastest and easiest way to test your NodeMCU ESP is the recall of device
number. Copy the following code or use the code example GetChipID from the
Arduino IDE:
To upload, click on the upload button from the Arduino IDE and hold down the
BOOT button on the SBC NodeMCU ESP32. The upload is completed unti the
writing has reached 100% and you willbe asked to reboot (hard reset viaRTS pin
…) with the EN key.
You can see the output of the test on the serial monitor.
