It is a DIY graphics calculator, with a CAS, an algebraic mathematical engine, so you can use it to integrate, derivate, and do matrix calculations. But if you dig into it a little, you will find an esp32, with Bluetooth and wifi connection. A Micropython implementation, an LVGL graphical library to develop a GUI, and you can access all of this from your computer, using your preferred developer environment, I suggest Thonny.
I fell in love with calculators, but no one was good enough, so I created my version.
It is open source, you can customize the GUI, the firmware, and create a new handheld device to feet your needs.
