I installed Openplotter for a Raspberry Pi 4 on a SSD SATA disc and put it in the "Argon One M.2" enclosure. The whole thing is connected to a 12 volt battery. A converter provides a stable direct current (DC) of 5.18 volt.
This setting works in principle. But not when I add some sensors to it. Obviously the sensors and USB devices are too much for the Raspi and it goes down. I suspect the power supply. Could this be the case? And how do I solve the problem?
An additional temperature and air pressure sensor is just fine. But if I connect a GPS mouse next or a receiver for AIS data, the Raspi goes to its knees, takes forever with every process, sometimes it seems to "freeze" while working.
What is the reason for this? Does anyone have an idea? And maybe a solution?
- The case "Argon One M.2"?
- To the SSD hard disk?
Is it possibly possible to operate the "power guzzlers" among the devices with a separate power supply?
Is it possible to make USB 3.0 plugs for the display and the SSD disc, where the current-carrying cables are virtually branched off, so that they don't have to be supplied by the Raspberry, but receive their current directly from the 5.18 volt power source?
Thanks for your help,

Technical background on my Raspberry Pi 4 installation:
Basic installation:
- Raspberry Pi 4, RAM: 8 GB
- SATA-SSD (M.2 SSD A400, 240GB)
- screen (9" high resolution display, capacitive touchscreen, HDMI)
- USB keyboard with mouse (one USB hub)
- Converter: from 12 volts to 5.18 volts direct current (DC) (these remain tested stable)
I would like to run these sensors:
- GPIO contacts: BME/BMP 280 for temperature, air pressure etc.
- USB: SDR receiver for AIS data
- USB: GPS mouse
