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.
What's On-Board?

I had used a lots of LoRa module till now, but it's really the best among all of them! the 1262 is a great upgrade in terms of output power and configuration. we can configure the output power, bandwidth, spreading factor and a tons of other things, which are not possible to configure on previous modules. the radiolib library works preety good with it and it also supports rssi and snr like features, which are very crucial when you are seriously researching on antenna or range related works! that's why I eventually like this module more then ebyte LoRas. To me this is the best module in IN8 68MHz, which is completly legal and free to use in India upto 1W! And also thanks to thinkrobotics, I got it in just 1 working day, and your packaging was also too good! Love your service, and keep this modules available on your websight. Your pricing of this module is too good, and I'll buy many of these modules. Thank you!

Team is suppotive and solves all the queries .
The product is good and will surely help me in my project...looking forward for more trades with think robotics.
