 The brain of the board is represented by an ESP32 microcontroller. This controller is very powerful and widely available at affordable prices. You can directly program it using the Arduino IDE or ESP-IDF. For lab lessons, you will use a serial communication interface between MATLAB Simulink and the controller to command the board.

+To use the DIY Power PCB, you can program the ESP32 using the Arduino IDE or the ESPRESSIFWorkspace (Espressif-IDE) development platform.
+Arduino IDE is more intuitive; however, it is not capable of utilizing the full range of the timer units. Espressif-IDE allows you to access the full functionality of the microcontroller, and the programmer is also faster than the Arduino IDE. However, it is more complicated to get started with.

+Following Bugs will be removed within V3 soon:
+  * Flashing only works if the incremental encoder is in the correct position, as it blocks the UART signal at every second rotation stage.
+  * The incremental encoder only works if the ESP32 is also supplied via USB.
+  * As the internal resistance of the driver is considerably high (200 Ohm), the bootstrap capacitor is only recharged slowly. This means that only duty cycle values of up to approx. 90% are possible. In V3 the problem is solved by an additional external bootstrap diode.
+==== General Information ====
+If you want to generate fancy 3D images you have to download the model files: {{ :professoren_webseiten:rebholz:htwg.3dshapes.zip | Download 3D Models}} \\
+The content of the .zip must be saved in the “3dmodels” folder of KiCAD in a new folder with the name “htwg.3dshapes”. \\
+If your PC does not recognize a USB-to-serial connection, you might not have installed the correct driver yet:
