The traditional Raspberry Pi is a single-board microcomputer that includes a lot of ports. The Compute Module 4 features the same processor as the Raspberry Pi 4, but it is especially for industrial use cases.
You can build a prototype using the traditional Raspberry Pi, and then order a set of Compute Modules to include in your commercial products.
Eben Upton wrote in a blog: We sell 7 million Raspberry Pi computers every year, and more than half of that amount is used. In industrial and commercial applications, from digital signage to process automation devices.
(Raspberry Pi 4) and Compute Module 4 are quite similar, such as ARM processor with VideoCore VI graphics.
The new computer represents a huge upgrade for previous Compute Module customers.
And you can get much better video performance by dealing with:
- 4K videos at 60 fps (H.265).
- 1080p videos at 60 fps (H.264).
- 1080p videos at 30 frames per second (H.264) standard.
You can also take advantage of the dual (HDMI) interfaces to connect up to two 4K displays at 60 frames per second.
You can also choose (Compute Module 4) with or without wireless technologies (wireless network and bluetooth), with 1, 2, 4 or 8 GB RAM, and 8, 16 or 32 GB of storage (eMMC).
There is also an eMMC model in case you want to use an external eMMC or an SD card interface.
You can choose from these specifications to reduce costs on a large scale, which means there is 32 different versions of Compute Module 4 range in price from $ 25 to $ 90.
And the shape of the microcomputer has changed compared to previous models, which means that you need a new I / O board for the Compute Module – at $ 35 – in order toTake advantage of all interfaces and start development.
