Waveshare Industrial IoT Wireless Expansion for CM4

The Waveshare Industrial IoT Wireless Expansion Module extends the capabilities of the Raspberry Pi Compute Module 4, providing a resilient platform tailored for industrial and edge computing environments. This module integrates essential connectivity options, including a Gigabit Ethernet RJ45 port for reliable network access, an HDMI output supporting 4K 30fps for display needs, and three USB 2.0 ports for peripheral integration. Its comprehensive design ensures the CM4 can be deployed in diverse applications requiring stable and high-performance I/O.

A key feature of this expansion module is its advanced wireless communication capabilities. It includes an M.2 B KEY slot and a Mini-PCIe slot (via adapter), enabling seamless integration of 5G, 4G, or LoRa wireless modules. A dedicated Nano-SIM card slot supports cellular communication, making it ideal for remote monitoring and IoT gateway solutions. Additionally, the module incorporates robust industrial interfaces such as two non-isolated RS485 ports and one non-isolated CAN port, facilitating integration with industrial control systems and sensor networks.

Further enhancing its industrial readiness, the module provides a real-time clock (RTC) with a battery socket for accurate timekeeping, a MicroSD card socket for CM4 Lite variants, and a versatile fan header for effective thermal management. These features, combined with its compact form factor, make the Waveshare Industrial IoT Wireless Expansion an optimal choice for building sophisticated, connected industrial and IoT systems based on the Raspberry Pi Compute Module 4.
