Cytron CM4 Maker Board is a carrier board for the Raspberry Pi CM4 or CM4 Lite system-on-module with plenty of I/Os, support for one M.2 NVMe SSD, and RTC backup battery, a buzzer, and various LEDs for GPIO status that makes the board especially well suited for the education market and prototyping.

The carrier board also comes with the usual Gigabit Ethernet and full-size HDMI port, four USB 2.0 ports, five Grove connectors, one Maker port, the omnipresent 40-pin Raspberry Pi GPIO header, and support power input from 7V-18V DC jack or 5V via a USB Type-C connector.
