3.3 Set up Development Environment
The Espressif IoT Development Framework (ESP-IDF for short) is a framework for developing applications
based on the Espressif ESP32. Users can develop applications with ESP32-C5 in Windows/Linux/macOS
based on ESP-IDF. Here we take Linux operating system as an example.
3.3.1 Install Prerequisites
To compile with ESP-IDF you need to get the following packages:
• CentOS 7 & 8:
1 sudo yum -y update && sudo yum install git wget flex bison gperf python3
cmake ninja-build ccache dfu-util libusbx
• Ubuntu and Debian:
1 sudo apt-get install git wget flex bison gperf python3 python3-pip python3-
venv cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0
• Arch:
1 sudo pacman -S --needed gcc git make flex bison gperf python cmake ninja
ccache dfu-util libusb
Note:
• This guide uses the directory ~/esp on Linux as an installation folder for ESP-IDF.
• Keep in mind that ESP-IDF does not support spaces in paths.
3.3.2 Get ESP-IDF
To build applications for ESP32-C5-MINI-1 module, you need the software libraries provided by Espressif in
ESP-IDF repository.
To get ESP-IDF, create an installation directory (~/esp) to download ESP-IDF to and clone the repository with
‘git clone’:
1 mkdir -p ~/esp
2 cd ~/esp
3 git clone --recursive https://github.com/espressif/esp-idf.git
ESP-IDF will be downloaded into ~/esp/esp-idf. Consult ESP-IDF Versions for information about which ESP-IDF
version to use in a given situation.

ESP32-C5-MINI-1 User Manual v1.0
3 Get Started
3.3.3 Set up Tools
Aside from the ESP-IDF, you also need to install the tools used by ESP-IDF, such as the compiler, debugger,
Python packages, etc. ESP-IDF provides a script named ’install.sh’ to help set up the tools in one go.
1 cd ~/esp/esp-idf
2 ./install.sh esp32c5
3.3.4 Set up Environment Variables
The installed tools are not yet added to the PATH environment variable. To make the tools usable from the
command line, some environment variables must be set. ESP-IDF provides another script ’export.sh’ which
does that. In the terminal where you are going to use ESP-IDF, run:
1 . $HOME/esp/esp-idf/export.sh
Now everything is ready, you can build your rst project on ESP32-C5-MINI-1 module.
3.4 Create Your First Project
3.4.1 Start a Project
Now you are ready to prepare your application for ESP32-C5-MINI-1 module. You can start with
get-started/hello_world project from examples directory in ESP-IDF.
Copy get-started/hello_world to ~/esp directory:
1 cd ~/esp
2 cp -r $IDF_PATH/examples/get-started/hello_world .
There is a range of example projects in the examples directory in ESP-IDF. You can copy any project in the
same way as presented above and run it. It is also possible to build examples in-place, without copying them
rst.
3.4.2 Connect Your Device
Now connect your module to the computer and check under what serial port the module is visible. Serial
ports in Linux start with ‘/dev/tty’ in their names. Run the command below two times, rst with the board
unplugged, then with plugged in. The port which appears the second time is the one you need:
1 ls /dev/tty*
Note:
Keep the port name handy as you will need it in the next steps.
3.4.3 Congure
Navigate to your ‘hello_world’ directory from Step 3.4.1. Start a Project, set ESP32-C5 chip as the target and
run the project conguration utility ‘menucong’.

cd ~/esp/hello_world
2 idf.py set-target esp32c5
3 idf.py menuconfig
Setting the target with ‘idf.py set-target ESP32-C5’ should be done once, after opening a new project. If the
project contains some existing builds and conguration, they will be cleared and initialized. The target may be
saved in environment variable to skip this step at all. See Selecting the Target for additional information.
If the previous steps have been done correctly, the following menu appears:
Figure 3: Project Conguration - Home Window
You are using this menu to set up project specic variables, e.g. Wi-Fi network name and password, the
processor speed, etc. Setting up the project with menucong may be skipped for “hello_word”. This example
will run with default conguration
The colors of the menu could be different in your terminal. You can change the appearance with the option
‘--style’. Please run ‘idf.py menucong --help’ for further information.
3.4.4 Build the Project
Build the project by running:
1 idf.py build
This command will compile the application and all ESP-IDF components, then it will generate the bootloader,
partition table, and application binaries.
1 $ idf.py build

If there are no errors, the build will nish by generating the rmware binary .bin le.
3.4.5 Flash onto the Device
Flash the binaries that you just built onto your module by running:
1 idf.py -p PORT flash
Replace PORT with your ESP32-C5 board’s serial port name from Step: Connect Your Device.
You can also change the asher baud rate by replacing BAUD with the baud rate you need. The default baud
rate is 460800.
For more information on idf.py arguments, see idf.py.
Note:
The option ‘ash‘ automatically builds and ashes the project, so running ‘idf.py build‘ is not necessary.
When ashing, you will see the output log similar to the following:

Host manufacturer must perform test of radiated and conducted emission and spurious emission, etc.,
according to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple
simultaneously transmitting modules or other transmitters in a host product. Only when all the test results of
test modes comply with FCC requirements, then the end product can be sold legally.
Additional testing, Part 15 Subpart B compliant
The modular transmitter is only FCC authorized for FCC Part 15 Subpart C 15.247 and that the host product
manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the
modular transmitter grant of certication. If the grantee markets their product as being Part 15 Subpart B
compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice
stating that the nal host product still requires Part 15 Subpart B compliance testing with the modular
transmitter installed.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
• This device may not cause harmful interference.

• This device must accept any interference received, including interference that may cause undesired
operation.
Caution:
Any changes or modications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This
device and its antenna must not be co-located or operating in conjunction with any other antenna or
transmitter. The antennas used for this transmitter must be installed to provide a separation distance of at least
20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or
transmitter.
OEM Integration Instructions
This device is intended only for OEM integrators under the following conditions:
• The transmitter module may not be co-located with any other transmitter or antenna.
• The module shall be only used with the external antenna(s) that has been originally tested and certied
with this module.
As long as the conditions above are met, further transmitter test will not be required. However, the OEM
integrator is still responsible for testing their end-product for any additional compliance requirements required
with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
Validity of Using the Module Certication
In the event that these conditions cannot be met (for example certain laptop congurations or co-location
with another transmitter), then the FCC authorization for this module in combination with the host equipment
is no longer considered valid and the FCC ID of the module cannot be used on the nal product. In these
circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the
transmitter) and obtaining a separate FCC authorization.
End Product Labeling
The nal end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC
ID: 2AC7Z-ESPC5MINI1”.
