What’s the good interface for use with a Raspberry Pi (4 or 5)? Holigram.io doesn’t seem to sell any interfaces like Nova and Dash any more, would something like Amazon.com work out of the box, or are there particular criteria involved in selecting a modem? USB woudl be a good interface in case I need to use it on another Linux system, but a HAT would also work.
I want to tell you that, for a Raspberry Pi a USB modem or HAT (Hardware Attached on Top) that supports your desired cellular network bands is ideal.
Look for modems with Linux support and drivers for easy integration…
Popular options include the Sixfab 3G/4G HAT or USB modems from brands like Quectel or Huawei, which generally work well with Raspberry Pi and Linux systems. Make sure compatibility with your network provider and check for proper driver support in the Raspberry Pi community or the manufacturer’s documentation.
