Raspberry Pi has announced new variants of the Compute Module 4 (CM4) with an extended operating temperature range, making them suitable for more demanding environments. While Raspberry Pi devices were originally designed for education, they are now widely used in industrial and embedded applications, where they must operate reliably under extreme conditions. The standard CM4 has been successfully deployed in various scenarios, but certain applications require operation below its minimum temperature of -20°C. To address this, Raspberry Pi is introducing new CM4 variants that can function in temperatures ranging from -40°C to +85°C.
The extended-temperature Compute Module 4 variants feature memory components from Samsung that are qualified for the broader range, while all other components remain unchanged as they are already rated for these conditions. These new models are available with different memory configurations, including options with and without onboard storage and wireless connectivity. Despite the added resilience, the modules maintain the same specifications as the standard CM4, including the Broadcom BCM2711 quad-core Cortex-A72 processor, HDMI and MIPI display interfaces, PCIe support, and a variety of GPIO options for industrial and embedded use.
The new variants ensure the CM4 can operate reliably in extreme environments such as outdoor installations in colder regions, industrial control systems, and even certain cold storage applications. While the most popular variants of the extended-temperature CM4 are available for immediate purchase through Raspberry Pi’s network of approved resellers, additional variants can be produced upon request, subject to a minimum order of 1,000 units. The lead time for these custom orders is approximately 10 to 12 weeks. For those requiring the enhanced temperature range, the new variants come at an additional cost. The extended-temperature CM4 models are priced $15 to $20 higher than their standard counterparts, making them a premium option for applications that demand greater resilience in extreme conditions.
