My absolute favorite has to be the Raspberry Pi 4 Model B combined with the Google Coral USB Accelerator. The processing power and versatility of the Raspberry Pi make it an ideal platform for many AI projects, and when you add the Coral USB Accelerator, you get the power of Google's Edge TPU, enabling efficient execution of machine learning models at the edge.
This combination offers a nice balance of processing power and ease of use, making it suitable for both hobbyists and professionals looking to develop and test AI solutions without investing in heavy server setups. Moreover, the community support for both Raspberry Pi and Coral is excellent, which makes troubleshooting and experimenting with new ideas easier.
Best of all, this setup won’t break the bank, making it a great way to get started with AI development without significant upfront investments.
