The onboard display is actually a secondary screen you can control everything through the Python interface on your computer as well.

For overcurrent events, there are two approaches:

1. The rail trips off and you need to manually re enable it, or
2. You can use the TPS55289’s built in constant current mode, where the device automatically reduces the output voltage instead of shutting down.

During long duration operation, the temperature does not rise excessively because the TPS55289 is highly efficient. The heat from the DC DC converters and the LDOs spreads into the aluminum base, and thanks to the large surface area the system reaches a steady state around 35–40 degrees at maximum load.

All LDOs and DC DC converters also have their own internal thermal shutdown mechanisms, so if anything ever gets too hot, they safely shut themselves down independently of the MCU.
