Waveshare CM4 vs XYGStudy IO Board
form factor
The Waveshare Raspberry Pi Compute Module 4 Lite is a compact system-on-module. Its dimensions are 2.17 inches in length, 0.39 inches in width, and 0.19 inches in height. It weighs 3.53 ounces. This small footprint allows for easy integration into tight spaces. In contrast, the XYGStudy Compute Module 4 IO Board is a baseboard. It is designed to hold the compute module. The IO board provides the physical connectors and structure. It does not have the same compact module dimensions. It is larger to accommodate the necessary ports and expansion slots for the CM4.
processor
The Waveshare unit features the BCM2711 processor. This is a quad-core Cortex-A72 (ARM v8) 64-bit SoC. It offers upgraded performance compared to previous generations. The processor is integrated directly into the compute module. The XYGStudy IO Board does not contain a processor. It is a passive interface board. It relies entirely on the compute module for processing power. Therefore, the Waveshare product provides the actual computing engine, while the XYGStudy board only provides connectivity.
memory
The Waveshare Raspberry Pi Compute Module 4 Lite comes with 2GB of RAM. This memory is soldered onto the module. It is ready for use immediately. The XYGStudy IO Board does not include any RAM. It is a development platform and reference base-board. It requires a separate compute module to function. The memory capacity depends entirely on which compute module you attach to the XYGStudy board. The Waveshare unit includes the memory as part of its specification.
storage
The Waveshare Lite version includes 0GB of eMMC flash storage. It is described as Lite, meaning it lacks onboard flash. It relies on external storage or network boot. The XYGStudy IO Board also does not specify any internal storage capacity. It serves as an interface for various storage options like NVMe or SATA via expansion. Neither product provides built-in storage in this configuration. The Waveshare module can use faster eMMC if you choose a different variant, but this specific Lite model has none.
networking
The Waveshare module includes WiFi connectivity. It supports either a PCB trace antenna or an external antenna. This makes it suitable for industrial applications requiring wireless connection. The XYGStudy IO Board provides networking ports through its design. It allows for the use of networking HATs or PCIe cards. It does not specify built-in wireless radios. The Waveshare unit has integrated wireless capabilities, while the XYGStudy board offers wired expansion options for networking.
