Seed Studio's CM4 modular board equips two high-speed gigabit Ethernet ports, two USBs 2.0, an HDMI port, a microSD slot, a GPIO interface for connecting additional Raspberry HAT add-on cards and a small 0.91-inch OLED screen. As a router, the module offers 32 options for dedicated storage, RAM and wireless functionality, along with OpenWRT already installed. However, it is also capable of running Ubuntu, Raspberry OS or any operating system compatible with this type of device.

The card is already available to purchase in the Seed Studio store at a price of $ 54.90 (€ 53.79), even if delivery times seem to be remarkably long: the site estimates a wait of 11 weeks.
The mods for Raspberry do not stop there, however, in the past we have already told you about a Japanese user who was able to turn an old camera from the 1950s into a digital video camera, thanks to the use of a Pi Zero 2 W card. A community of enthusiasts was able to create something even more extravagant, using a Pi 4 to make the Terminator brain.
