@justRobsi this sounds like a power issue. When installing packages the wifi radio is working to download the files, the CPU is writing the download to RAM, etc. There's a lot going on so the power draw increases significantly and sharply. To get over this hurdle during development, I recommend either: Using an Omega2S Development Kit - it allows for swapping Omega2S modules and has the required power circuit Getting a (through-hole) Omega2 or Omega2+ and a Dock for your development - this will eliminate any power supply issues And then when making your own circuit to power the Omega2S, please refer to the Omega2S Hardware Design Guide and the Omega2S reference schematic
