MaixSense R329 Kit
The MaixSense R329 Kit is the perfect solution for your hobbyist needs. Whether you're exploring robotics or artificial intelligence projects, this kit comes with everything you need to power your idea.
MaixSense is a really small Linux card computer. Its package contains a SOM(System-on-Module) based on R329 and a multifunction IO expansion bottom board. Running Linux OS, it can be used for personal servers, Intelligent voice assistants, or robotics. Because of the AIPU npu core, this board can also be used for intelligent voice and video image processing, and AI model like CV, and NLP can also run on it.
R329 is a 64 bits processor designed by Allwinner containing dual Cortex-A53 inside, with 2 HIFI4 DSP used for audio pre-processing and post-processing, containing an extremely low energy consumption AIPU (Artificial intelligence processing unit) whose hash rate over 0.256 TOPS designed by ARM China, can be used to accelerate neural network, dealing with the 720P image captured by the camera.
