Waveshare Industrial IoT Wireless Expansion Module for Raspberry Pi CM4
Note! The product is delivered without CM4 and mobile module.
This is an industrial expansion module based on Raspberry Pi CM4, which features common interfaces such as Gigabit Ethernet, HDMI, USB, and GPIO, allows additional 4G / 5G / LoRa wireless communication modules to be connected via the M.2 or Mini-PCIe socket. There are also industrial interfaces/resources including RS485, CAN, and RTC.
Combined with the industrial rail-mount protection case, the module is an ideal choice for building IoT gateway, 4G/5G router, IoT data acquisition, or even the PLC device in industrial automatic control system, and more.
An additional communication module is required to enable 5G/4G/3G/2G cellular network or LoRa gateway function!
Features
- 4G/3G/2G communication, GNSS positioning, global coverage
- Standard Mini-PCIe interface, high compatibility
- Multi-constellation high accuracy positioning GNSS receiver support
- Suitable for LTE, UMTS, and GSM network with global coverage
