Here are some ways you can upgrade your Raspberry Pi using hardware add-ons.
1.Fast SSD storage
If you're sick of the Pi being bottlenecked by its slow SD card storage, you've got options, such as adding a fast Solid-State Drive (SSD).
2.Machine learning accelerators
Machine learning has proved its worth in teaching computers how to recognise images, speech and language.
While the Raspberry Pi struggles to carry out machine learning on its own, there are USB accelerators that give the Pi sufficient power to handle a range of computer-vision tasks.
3.Power over Ethernet
The official Power over Ethernet (PoE) HAT is an add-on board that sits on top of the Raspberry Pi 3 Model B+ and allows the computer to be powered using an Ethernet connection.
