Hardware List

Sketching with hardware requires some hardware components. To create a functional prototype, we typically need a microcontroller, sensors, actuators, and components to link the parts together.

Only a small set of parts is required to get started and follow the course. You can do many of the exercises and tutorials with only a microcontroller (e.g., ESP32, ESP8266), a few LEDs, and some resistors. We recommend getting started, and once you like building things, then get a hardware kit.

In the following list, we marked the components in the LMU hardware box with LMUBox.
