Raspberry Pi Compute Module 4 (You can choose RAM eMMC WiFi) The CPU is upgraded to BCM2711, and the quad-core CortexA7264-bit processor is more powerful. More memory is available, 1GB/2GB/4GB/8GB, suitable for large-scale data compilation. Higher-speed eMMC flash memory, peak eMMCbandwidth100MBytes/s is four times faster than CM3+. . The wireless module option is added, and the WFI Bluetooth module is the same as PI4B, and the on-board PCB antenna and external antenna are provided, which is more suitable for industrial applications. Adopting B to B connector design, changed the golden finger design of previous generations of CM series, and increased stability. The new size is 55*40*4.7mm, which is more suitable for compact design. Increase the onboard dry Ethernet design to support EE1588, which is suitable for network application development. Increase the expansion of the PCle interface, and can flexibly add related modules.
Connectivity:
Optional wireless LAN,2.4GHz and 5.0GHz IEEE 802.11b/g/n/ac wireless, Bluetooth 5.0, BLE with onboard and external
antenna options. Onboard Gigabit Ethernet PHY supporting IEEE1588. 1 × USB 2.0 interface. PCle Gen 2 x1 interface. 28 GPIO signals. SD card interface for SD card or external eMMC (foruse only with Compute Module 4 variants without eMMC).
