Well, I started this project here… the idea I had was to make a node that is a ‘calculator’ from scratch. I’m not exactly sure if I’ll include multiple buttons or common functions in it, because the difference with this one is having access to the AI API, and I’m also thinking about adding Wolfram Alpha. It’s going to have a camera to take a picture of the equation, send it to the API, and it returns an image of the solution. It connects to Wi-Fi and sends the data to a server where it’s processed, formatted in LaTeX, and then returns the image.

So I started by putting the components in the EasyEDA schematic and created a simple device that was supposed to be the Seeed Xiao ESP32 S3
