Grove Vision AI Module contains a camera (OV2640) and two microcontrollers.
- Himax HX6537-A is an ultra-low-power, high-performance microcontroller designed for battery-powered TinyML applications.
- BL702 32-bit RISC CPU. BL702 is the USB-UART chip which enables the communication between the PC and the Himax chip.
In addition, there are two sensors:
- Micropone MSM261D3526H1CPM
- 3D Accelerometer and gyroscope, 6-axis Inertial Measurement Unit (IMU)
Dual 7-pin headers are compatible XIAO series boards.
Operating Voltage 5v.
Baud rate 115200.
I2C interface.
The camera supports resolution up to 1600x1200 px but is set to 192x192 px due to the limitation of inference speed.
It is not open source product. Link

Linux may not recognize it as a USB device. Therefore we need to create new rules file. File name: 60-visionai.rules
File content:
SUBSYSTEM=="usb", ATTRS{idVendor}=="2886", ATTRS{idProduct}=="8060", MODE="0666"
Save the new rules file to the /etc/udev/rules.d/ directory.
Restart the udev rules:
sudo udevadm control --reload-rules
