What is it?

The SEM can be used as a STEM learning device. Excellent to use with a collection of 37+ sensors!

The heart of the SEM is a 32-bit microcontroller (PIC32MX) with an integrated advanced program interpreter. The language that SEM uses is a modern version of BASIC. Unlike past versions of the language, this new BASIC is structured. It supports subroutines and doesn't need line numbers. It is the perfect language for the SEM. It is easy to learn, and yet still powerful. It has support for the input and output control that the SEM needs.

The SEM has I/O lines along the top edge of the PCB for connection to various circuits. The SEM can be used with a solderless printed circuit board for prototyping. The SEM can also be used with other electrical connection methods to interface to modules, devices, and circuits.

Why did you make it?

There are 37-sensor kits that you can get that have a lot of different sensing and control modules. I made this board in order to make it easy to learn about these sensors and use them for experiments.

The SEM has a graphic display and three colored buttons for user I/O. Control and programming of the SEM are done through a USB-to-PC connection.
