I have a Magni which I had not used for a while. Recently I tried to run it with my Raspberry Pi 4, running the Ubiquity Robotics Magni image and the board was unable to power the Raspberry Pi. Upon checking, I found out that the 5V Main supply LED was off while the rest of the three LEDs (12V Aux, 12VMain and 5V Aux) were on. The status LED was also off. The board I have is rev 5.3 and I have attached a picture as it looks when both the main switch and the motor switch are turned on.
I am not sure why this is happening. Would really appreciate any help on this.
