Raspberry Pi Compute Module 4 gets rugged upgrades

Since its launch, the Raspberry Pi Compute Module 4 has become a juggernaut in the SBC space for both consumer and industrial applications. The Raspberry Pi site alone has many testimonials of how the SBC has made its way into a variety of applications, whether that is as an industrial computer with Revolution Pi, an energy management solution with EpiSensor, or even as a point-of-sale system with KwickPOS. However, not all projects will meet the current operating temperature of between -20°C (-4°F) to +85°C (185°F), especially when used outdoors or in intense industrial settings. Fortunately, the new extended temperature range Compute Module 4 tackles this issue.

With a wider temperature range of -40°C (-40°F) to +85°C (185°F), the extended temperature range Compute Module 4 is tailored to meet the demands of the growing industrial applications of the SBC. In addition to all of the onboard components being ruggedized, the new Compute Module 4 also features new SDRAM and eMMC parts from Samsung that meet the new temperature demands of the SBC. However, in addition to minimum order requirements, the new Compute Module 4 comes at a premium.

Currently, the base model variant for the extended temperature range Compute Module 4 comes in at $50 vs the $30 standard temperature range, with both featuring 1 GB of RAM and no wireless networking or eMMC storage. Maxing out the specs of the new Compute Module 4 brings the SBC to $80 vs $65 and brings 4 GB of RAM, wireless networking, and 16 GB of eMMC storage. Interestingly, the standard temperature range modules offer a few higher-spec variants that are not currently available for the new module.

While the new Compute Module 4 is a relatively niche product, it is sure to find its way into some unique and interesting applications. Curious makers can find more information on the new Compute Module 4 and purchasing options in the resources below.
