Petoi AI Vision Module is based on the Arm Cortex-M55, and Ethos-U55 embedded vision module. The Ethos-U55 has 64 to 512 GOP/s of arithmetic power to meet the growing demand for downloading machine learning.
Fix the end connected to the camera to the robot's head (included in Bittle's / Bittle X's mouth or attached to Bittle X+Arm's robotic arm).
There are two methods to upload the firmware :
Using the Petoi Desktop App
Using the Arduino IDE
You can use the within the Petoi Desktop App.
Please select the correct Product type, Board version, and Serial port according to your actual use. The mode should be Standard, so press the Upgrade the Firmware button. For example, Bittle, BiBoard_V0_2, COM5 as follows:
For more details, please refer to .
After uploading, there are two methods to activate/deactivate the camera mode:
Serial Monitor
and use the serial command "XC" to activate the camera mode.
Open the serial monitor and use the serial command "Xc" to deactivate the camera mode.
Mobile App
Combined with the empowerment of the web debug GUI (), you can easily upload a wide variety of co-created models and directly observe the results.
For how to use this web debug GUI, please refer to:
To run the example code (inference.ino) in the library , you should add the library to your Arduino IDE by selecting Sketch > Include Library > Add .ZIP Library and choosing the downloaded file.
Or you can install the library in the Library Manager of the Arduino IDE as follows:
The Petoi AI vision module also supports taking photos and transmitting images via Wi-Fi, but it needs to be installed on a MCU with more powerful computing power (such as ESP32S3, ESP32C3, etc.). For the specific development process, please refer to the wiki technical documentation:
Create a mobile app command called "Activate camera" and use the code: X67
Create a mobile app command called "Deactivate camera" and use the code: X99
