TI CC1352P Launchpad
The Texas Instruments CC1352P Launchpad is a development board equipped with the multiprotocol wireless CC1352P microcontroller. The Launchpad, when paired with the BOOSTXL-SENSORS booster packs, is fully supported by Edge Impulse, and is able to sample accelerometer & microphone data, build models, and deploy directly to the device without any programming required.
If you don't have either booster pack or are using different sensing hardware, you can use the Data forwarder to capture data from any other sensor type, and then follow the Running your impulse locally tutorial to run your impulse. Or, you can clone and modify the open source firmware-ti-launchxl project on GitHub.
To set this device up in Edge Impulse, you will need to install the following software:
With all the software in place it's time to connect the development board to Edge Impulse.
To interface the Launchpad with sensor hardware, you will need to either connect the BOOSTXL-SENSORS to collect accelerometer data, or the CC3200AUDBOOST to collect audio data. Follow the guides below based on what data you want to collect.
Before you start
The Launchpad jumper connections should be in their original configuration out of the box. If you have already modified the jumper connections, see the Launchpad's User Guide for the original configuration.
Connecting the BOOSTXL-SENSORS board to the Launchpad is simple. Just orient the sensor board such that the
GNDmarkings on the booster pack line up with the Launchpad, and then attach the booster pack to the top header pins of the Launchpad, as shown below:
Extra Hardware Required
The CC3200AUDBOOST board requires modifications to interface properly with the CC1352P series of Launchpads. The full documentation regarding these modifications is available from Texas Instruments in their Quick Start Guide, and a summary of the steps to configure the board are shown below.
- 1.Disconnect conflicting pins on the Launchpad.
Pins 26-30on header
J3conflict with the CC3200AUDBOOST pins and need to be disconnected. To do this easily, TI recommends bending the pins down as shown below.
Launchpad modifications are compatible across booster packs
All Edge Impulse supported booster packs do not use
pins 26-30on header
J3. If you have modified your Launchpad to interface with the audio booster pack, you can leave these pins disconnected when connecting other boards.
- 1.Connect jumper wires to the required pins
With the pins connected, your board should appear as shown below.
- 1.Align the
P1pin on the booster pack with
3V3pin on the Launchpad, and connect the two boards together.
In most cases it is possible to connect the sensor and audio booster pack at the same time. Allowing you to quickly switch between accelerometer and audio data collection. The primary constraint is that the BOOSTXL-SENSORS board must not have the TMP007 temperature sensor soldered on, as this conflicts with the audio interface when both booster packs are connected.
- 1.Ensure that the TMP007 temperature sensor is not present on the sensor booster pack. The board should have an unpopulated footprint for
U5as shown below:
- 1.Connect the audio booster pack on top of the sensors booster pack. The final board should appear as shown below:
2. Connect the development board to your computer
Use a micro-USB cable to connect the development board to your computer.
3. Update the firmware
The development board does not come with the right firmware yet. To update the firmware:
- 2.Open the flash script for your operating system (
flash_linux.sh) to flash the firmware.
- 3.Wait until flashing is complete, and press the RESET button once to launch the new firmware.

3. Setting keys
From a command prompt or terminal, run:
This will start a wizard which will ask you to log in, and choose an Edge Impulse project. If you want to switch projects run the command with
Which device do you want to connect to?
The Launchpad enumerates two serial ports. The first is the Application/User UART, which the edge-impulse firmware communicates through. The other is an Auxiliary Data Port, which is unused.
When running the
edge-impulse-daemonyou will be prompted on which serial port to connect to. On Mac & Linux, this will appear as:
? Which device do you want to connect to? (Use arrow keys)
❯ /dev/tty.usbmodemL42003QP1 (Texas Instruments)
/dev/tty.usbmodemL42003QP4 (Texas Instruments)
Generally, select the lower numbered serial port. This usually corresponds with the Application/User UART. On Windows, the serial port may also be verified in the Device Manager
Alternatively, recent versions of Google Chrome and Microsoft Edge can collect data directly from your development board, without the need for the Edge Impulse CLI. See this blog post for more information.
4. Verifying that the device is connected

With everything set up you can now build and run your first machine learning model with these tutorials:
Failed to flash
If the UniFlash CLI is not added to your PATH, the install scripts will fail. To fix this, add the installation directory of UniFlash (example
/Applications/ti/uniflash_6.4.0on macOS) to your PATH on:
If during flashing you encounter further issues, ensure:
- The device is properly connected and/or the cable is not damaged.
- You have the proper permissions to access the USB device and run scripts. On macOS you can manually approve blocked scripts via
System Preferences->Security Settings->Unlock Icon
- If on Linux you may want to try copying tools/71-ti-permissions.rules to /etc/udev/rules.d/. Then re-attach the USB cable and try again.
