This is a dual Gigabit ethernet 5G/4G base board from Waveshare, designed for the Raspberry Pi Compute Module 4 (not included).
This base board's main features are the dual-Gigabit Ethernet ports, allowing you to evaluate the CM4 as a controller for a custom router project. You'll need to compile your own software for this with very limited information from the manufacturer, so this is not intended for novice users!
There's also a slot for an SIM7000G-H M.2 B-Key 4G/5G module (not included) allowing the addition of LTE functionality for your project. Alongside this is a nano sim card slot option 5G/4G/3G/2G connectivity as well.
The board also features 2x USB 3.2 ports, an RTC and backup battery holder, fan header, 2x CSI and 1x DSI ports, 2 full-size HDMI ports and a Micro-SD card slot!
Base board only. Does not include the CM4, power supply or M.2 B-Key module. This allows you to choose your wireless and power options separately.
