Compute Module 4S

High speed, low power consumption

Compute Module 4S is based on the Raspberry Pi 4B architecture, making it easy for users to migrate or upgrade from Compute Module 3/3+

New upgrade, more powerful CM4S

The CPU has been upgraded to BCM2711, a quad-core Cortex A72 64-bit processor with stronger performance
and faster eMMC flash memory, with a transfer rate of up to 100 MB/s, which is 4 times faster than CM3+.
