Orange Pi CM4 Module: Raspberry Pi CM4 Clone

The Orange Pi CM4 (Computer Module 4) is a compact and powerful computer module that is compatible with Raspberry Pi CM4 (Compute module 4).

Last couple of years we have seen how crazy it was to find a Raspberry Pi CM4 module, my own customer projects got delayed due to availability issues.

I am quite happy that now these alternatives or clones, whatever you may want to call, are coming up in the market and will be able to serve the applications.

The Orange Pi is already a well established brand now in Single board Computer domain, they have a lot of good boards with documentation and support.

Orange Pi CM4 module is powered by a quad-core 64-bit Rockchip RK3566 processor, has 1GB/2GB/4GB/8GB of LPDDR4/4X RAM, and supports up to 128GB of eMMC flash memory. It also has a variety of I/O ports, including HDMI, USB, Gigabit Ethernet, and Wi-Fi 5.

The Orange Pi Compute Module 4 is a good choice for a variety of deep embedded applications, such as industrial automation, smart home devices, robotics, machine vision, medical devices, and automotive electronics. It is also a good choice for developers who want to create custom embedded systems.

The Orange Pi Compute Module 4 is open source and has a large community of developers. It is a good option to consider if you are looking for a compact and powerful SBC for deep embedded applications.

I would definitely like to buy one or two of these modules and try to compare how compatible they are with the Raspberry Pi CM4 module especially when connecting to different carrier boards.

I am sure there will be some differences between them, but it would still be interesting to see how they compare.
