PCIe to M.2 4G/5G & USB 3.2 HAT+ Expansion Card — M.2 Key B Interfaces, Fast Data Transfer

This expansion card converts a PCIe connection to M.2 Key B Interfaces for 4G/5G modules and adds HAT+ USB connectivity for faster data transfer. Built to work with RPi 5, the HAT+ standard PCIe interfaces can connect directly to the RPi 5 via a 16PIN cable. It offers a 3-way USB 3.2 PCIe expansion and USB 3.2 Gen1 high-speed interfaces to attach multiple devices easily. An onboard power monitoring chip measures current and power parameters in real time, and status LEDs for the card slot, power and networking make debugging and status checks straightforward. Compatible with matching customized 5G 4-in-1 modules to keep wiring tidy, the board also provides reserved ventilation and fan mounting holes (top or bottom) and air ducts to boost airflow and lower module temperature. Ideal for desktop or home office setups that require additional cellular connectivity and expanded device access.
