Raspberry Pi 4 & USB MBB dongle
The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote teaching of basic computer science in schools and in developing countries. It is widely used by Device Developers. By extending the board with a USB Mobile Broadband, it becomes a very flexible IoT device development tool.
