  Imagine a Raspberry Pi that doesn’t need to hunt for a Wi-Fi password. Imagine a project that works in the middle of a farm, inside a moving vehicle, or at a remote weather station. As makers and engineers, we love the Raspberry Pi for its versatility. But let’s face it: its reliance on Wi-Fi or Ethernet is a leash. Cut that leash, and your Pi becomes truly powerful. Enter the Quectel EC200U 4G LTE USB Modem. I recently explored this industrial-grade communication module, and here is why it’s becoming a staple for serious Raspberry Pi enthusiasts: 1. True Remote Independence The EC200U isn't just a dongle; it's a gateway. It supports LTE-FDD, LTE-TDD, and GSM/GPRS. This means your Pi can upload telemetry data, send alerts, or host a web server from virtually anywhere with cell service. No more "Out of Range" errors. 2. Plug-and-Play Simplicity for Linux One of the biggest headaches with cellular modems is driver compatibility. The Quectel EC200U is designed with L...
