S2 Power Board

The S2 Power Board is a all-on-one development board designed for primary and secondary students to explore the world of mechatronics!

Traditionally, the barrier for learning how to use microcontrollers like Arduino or the ESP32 is quite high due to messy circuitry and power supplies requirements (servos in particular). The S2 Power Board aims to address this by taking care of the support circuitry on the PCB. Students can start tinkering right away programming with their choice of Arduino C++ or CircuitPython.

The S2 Power Board can be used along side with the Teachable Machine Interface App, adding Computer Vision AI functionalities to the students’ project with relatively little effort. Tutorials for developing image classification projects like Recyclable Waste Sorting will be available soon.

With the S2 Power Board, students can learn core electronics and machine learning concepts, then easily integrate them to their project use-case creatively!
