PINE64 SOQUARTZ-4G is a 4GB CM4 Compatible Single Board Computer, with the same pin out, to drop into a main board. It has the RK3566 Quad Core CPU, 4GB of RAM, WIFI and Bluetooth, I believe a single HDMI out, with other display connector compatibility, alongside Gigabit Ethernet compatibility etc. Feel free to ask any questions! Have a nice day!
