While the Raspberry Pi project has its origins in education, the majority of Raspberry Pi computers we make today are destined for industrial and embedded applications. To address these applications, our products need to perform flawlessly in harsh environments – subject to extremes of temperature or pressure, or running unattended for years on end in remote or inaccessible locations.

Raspberry Pi Compute Module 4 has been used successfully by thousands of embedded customers in a wide variety of challenging environments. But there are geographical locations where outdoor winter temperatures fall below the -20°C minimum operating temperature specified for Compute Module 4, and certain indoor applications also require correct operation at very low temperatures.

To support our customers in designing products for these demanding conditions, today we are announcing several new Compute Module 4 variants, with an extended operating temperature range of -40°C to +85°C. These variants integrate extended-temperature-range SDRAM and eMMC parts from our partner Samsung; all other components on the board are already qualified to the broader temperature range.

We are offering variants with and without wireless connectivity, and with a range of SDRAM and eMMC densities. A core subset of these variants is available to purchase from stock from our network of Raspberry Pi Approved Resellers, while others can be built to order, subject to a minimum order quantity. You’ll find a full list of variants, including their prices, in the Compute Module 4 product brief.

With Raspberry Pi technology providing high-quality, low-cost compute everywhere from the Antarctic to the ocean floor to low Earth orbit, we’ve seen a fair few exotic deployments, but we suspect our customers will build things with Compute Module 4 extended temperature variants that will nevertheless surprise us!
