Hardware List

List of Hardware Components

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

To get started and to follow the course only a small set of parts is required. 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 have marked the components that are in the LMU hardware box with 'LMUBox'.

Microcontroller

• ESP32 Web Kit with integrated OLED Display from Heltec LMUBox
• ESP8266 ESP-12F NodeMCU Module from AZDelivery LMUBox
