描述
2020全新樹莓派運算模組 CM4 (非無線)
The Raspberry Pi Compute Module 4 (CM4) leverages the computing power of the popular Raspberry Pi 4 Model B, with dramatic performance changes compared to its predecessor: faster CPU cores, better multimedia, more interface capabilities. And for the first time, this release offers multiple choices of RAM density and wireless connectivity options.
In terms of external dimensions, this version adopts a completely new mechanical standard. The overall footprint of the module on its carrier board is reduced, resulting in a smaller and more compact form factor suitable for integration into products.
For storage, the Raspberry Pi Compute Module 4 (CM4) has an optional 8GB, 16GB, or 32GB onboard eMMC, which is different from the Raspberry Pi 4’s Micro SD card slot.
This version of the Raspberry Pi Compute Module 4 includes a high-performance 64-bit quad-core processor, 8GB LPDDR4 RAM, dual monitor support up to 4K resolution, hardware video decoding up to 4Kp60, Gigabit Ethernet, USB 2.0, dual camera interfaces, PCIe Gen 2 x1 interface, dual-band 2.4/5.0GHz wireless LAN and Bluetooth 5.0.
